This isn’t acceptable
You have supplied something which isn’t compatible with each other.
I understand the reasons to why you may bundles items into your theme, but in turn you than have to accept a level of responsibility to how compatible it is or don’t supply it, falling back on third parties is not acceptable, if you have paid a license to supply this item, then you also have a right to demand it gets sorted or fix it yourself
Turning it off, because it doesn’t work, isn’t really an answer is it, I have around 10 licenses with you, how long will it be until the other clients spot things don’t work
You can re-write the code as you know you can, but it’s easier to pretend it’s not your problem when it very much is
I suggest you get someone a bit more senior to look at this and if you are bundling plugins together, make sure they are compatible with each other, thats what we pay for this theme for
