Yes, I also found this affects multiple marketplace texture packs being used at once

It would be really good if we could specify which parts we want from marketplace packs, some I just want the mobs, others I want the blocks, and some I want to use for the blocks that haven't been updated yet on my main texture pack

Incompatibility between third-party content (your custom pack) and marketplace content is not a bug in the game.
