Could you provide some more information please? Like a screenshot?
We are getting the lines in the bleed & never got them until the upgrade

One of the recent updates added transparent/white outline around the crop marks, so they are visible say on black bleeds. That's what you probably see. On your screenshot there are multiple crop marks and I am not sure which exactly you don't want to see (or just surprised to see). Please point to the line which you think is wrong and let me know why. It would also help to see a small PDF with the lines that we can check and see what exactly happens.
