SquidGuard Bug when add many TargetCategories

[MPFontana]

Guys I'm facing a wierd bug:

When I add many TargetCategories and them pass of a x number of character's, on Common ACL, the TargetRules List just goes out. When I delete any of my TargetCategorie, so it show's up again.

I've already reinstaled the whole Pfsense.

See the images.
