Sorry for the delay Vurse, I don’t have the bandwidth to review every UI element of each game from the QA reviews. I did however find some time to go over your QA review and your game and I have some thoughts on this issue.
Although your UI elements are huge (comically so for the 4 shop items) the text for “shop” is quite small. If you are going to size a comically large box, make sure the text actually fills out the box. I also noticed the screenshot on the review is not your current system, so it may have not been updated. This is why its important to submit full fixes to me for an official re-review when you think all systems are fixed.
Another element of the process is that not all QA reviewers are 100% familiar with ROBLOX systems. So even though you are using a default ROBLOX system and think its fine, they may not know its default and thus fail the system. Your global level leader board for example is just too tiny, I’m not sure if this is included on Xbox, but there is no way this system will pass cert or QA if it is.
