So drop more calories, you are still eating above what you are expending. Like I said in another comment: our bodies aren't supernatural things that ignore thermodynamics, it's impossible for your body to create fat without spare energy consumed.

I have dropped weight only through calories counting, I've done cycles of bulk/cut while weightlifting, dropping weight boils down to "calories in -> calories out", we might not have a very good model of this, we might be overlooking a multitude of variables that control energy expenditure but we can't create fat from nowhere, we need to consume and have spare energy to store it.

It's not easy but it is simple. Again: I'm not saying our models for calculating TDEE or how energy restriction affects our body completely but if you are expending more calories than you are eating you are going to consume fat to create energy.

Try this: drop how many calories you are eating by another 100~200kcal/day for a week, see if the trend changes (a moving average works). If not, drop another 100~200kcal/day and watch for a week. Being STRICT is the "not easy" part.
