Insane progress bud! Keep it up, you are doing awesome.
Dont get hard on yourself about your weight lifting not getting a lot of improvement. It is next to impossible to gain muscle when losing fat due to the fact that you need more calories then your BMR to gain muscle and when losing fat you are obviously taking in less calories then your BMR. For those of you shedding fat, aim on maintaining your strength. In your case you not only are maintaining, you actually can lift a tad more then when you started. Perfect job!
