Error in Reports upgrading to 7.6

I´ve upgraded from ver 7.4 trough Softaculus, but when I try to modify or edit reports (news and existings) I cannot setup the conditions, the button is not operating . I tried with Admin account and not result. Apparently the other menus and tabs works well. Thanks in advance.

The issue

has been finished with the 7.6.3 upgrade to.
