You have the tracker set to adjust your calories according to how much exercise you've done (over and above "just existing" and normal daily activities); that's why it keeps changing. If you find that annoying and hard to deal with, it is possible to modify the tracker to give you an average daily calorie range based on estimates of how much exercise you will do overall. I don't know how to set that up myself, but I'm certain someone will come along to explain it if you indicate that's what you'd like to see.
Assuming that your exercise for the week is such that, on average, you are burning a total of about 2300 calories a day -- and further assuming that you are female -- then you are eating too little for your activity level. 2300-1000 (the deficit needed for a loss of 2 pounds per week) is 1300, and you're mostly not getting that. Further, the bare minimum in calories that a normal woman can take in and still get all of the required nutrients is about 1200, and you're not averaging that high, either.
I don't know what it is metabolically that does it, but the type of problem expressed in your post -- bare-minimum calories or lower, plus substantial exercise, plus little to no weight loss -- seems to come up here infinitely more often than does the reverse -- moderate calories, with no exercise, and little to no weight loss. It might not be just chance; you may actually be stressing your body too much.
When I came here, I set up my tracker for a more moderate loss of just one pound per week, doing a comparable amount of exercise daily, and was given a range of something like 1500-1800. So best I can tell (as I've never tracked, just done the occasional spot check), I stayed within that range, but actually lost closer to 1.5 pounds weekly. I could not imagine having tried to stay 500 calories below that in search of that elusive last half pound; I don't think it would have been good for me.
So please consider eating a bit more, maybe around 1500 to begin with, so that you can meet your nutrient needs and give your body enough energy to maintain that level of healthy exercise over the longer term without rebelling on you, whether sooner or later. There would be nothing whatsoever wrong with then cutting that by a couple hundred calories daily in a month or so if you're not getting the desired results. But you well might, and either way you won't be setting yourself up for trouble like you're doing now.
Finally -- the other commonality I've noticed among people who come here eating not-so-many calories and exercising, yet not losing weight, is that many of them are getting a substantial fraction of their not-so-many calories from "empty" sources. If that happens to be true for you, then improving the nutrient profile of what you're eating may also be helpful to your weight loss efforts. I'm not too huge on the whole "eat THIS or you won't lose weight/don't eat THAT or you won't lose weight" idea, but on some level it's undeniable that it takes a few more calories for your body to work through a big bowl of salad than it does to digest a handful of potato chips. So if that applies, maybe give it a look.
