Hey manoelneto,
Thanks for providing that repro! I was able to get it to occur in house and it appears we’re already looking into it with UE-21203.
It took me about 20 function tabs to repro, but it appears that it is an issue directly related to the size of the tabs. I could make only 5 functions, but squish the blueprint window size until they were very small. We’re actively working on a solution, but for now, at least you know what the exact repro is and can hopefully try to avoid it.
