League Major Issue

I encountered Major issue with League. It creates a brackets same way a Round and Robin. The issue is it supposed to be Double Round and Robin – it League! I did check plugin code. Looks like it is missing just few lines of code. I would add them by myself but code was customized by your developers and my knowledge od PHP does not Reach do far. Can you please post for us these missing lines that create “revert” in League Please? It is most important Feature for my website and now it holds us with start! Thank you in advance.
