Pocket has zero max volume?

I recently booted up the latest experimental branch after not playing for a couple of months. I have worked out all bugs except bugs saying mags don’t have a max volume. I couldn’t see what I have wrong at all. I’ve looked at the game’s code as far as I can tell, it’s the same except certain parts.
Here’s the code for one of the mags that’s messed up. Below I’ll have the respective gun in case thats the issue.
