Bulk Lock/Unlock match and match creation problem

Hello,

few versions ago i made a custom script to lock and unlock match in bulk. Actually with the new version it’s not working and i would like to know if you or someone else can help me finding what is wrong. The custom code added can be found looking for “Pulze” in the file left as attachment and i leave even a file where i tried to put the custom code in the new version file (2.6.3) but wihtout make it working.
Also could be a good idea if this would be a part of the official theme in future versions.

As last i noticed that when you want to create a match from backend it’s possible between teams but not between users seen that you can’t choose the opponents. Here what i get: http://prntscr.com/ng99f6

Edit: i can’t upload files don’t know why… here the link to them anyway https://github.com/roberto722/files-arcane
