Delete button greyed out in CQ5.3 after installing feature pack

[Rich_Clem]

On one of our development environements for CQ5.3 we have just installed feature pack cq-5.3.0-featurepack-37434-4. Now for some reason we cannot delete pages even as administrator. According to CQ this user should have permissions to do this. Any suggestions? Thanks

Workarounds would be Delete from crx explorer Or uninstall the package. 

P.S:-  CQ 5.3 declared EOL.
