Took an initial look.

• Theres a few items that are popping up that should not be there. Azerite pieces (think I noticed the cloth shoulders from mechagon). And a few legendary items from karazhan? Might be others, but this was a very quick ingame look on my part.

• I'm abit worried about the usage of genericly named, public functions. You might want to look at using local functions to avoid any possible problems. Or, if you want them global, change to more uniquely named functions.
