Wah on full heel chokes distortion tone

I have V847 wah placed after a DS-2 and homemade OD pedal, when the DS-2 is on it chokes and cuts off a lot of the distortion and sound when on full heel. In the video you can see for some reason 12 feet G-String full heel doesn’t really cut off distortion as much as everything else. The choking is less prominent but there when it is just the OD and the wah. The V847 is an old 90s Made in USA that i modded for true bypass and a 9V power supply. The problem mostly goes way when i place the pedals after the wah but I wanna like the extended sweep with again before wah so I wanna keep that. My chain is: small shitty AC-10 amp > Small clone > V847 > DS-2 > OD pedal > Jaguar on neck humbucker.

Any solutions or is this just how wah acts?
