Site Wide Text Change - Certain Widgets Tittles Not Changing

Hello,

I have a Multi Site with Buddypress installed using the Ultimate Branding to change certain words at the backend of my subsites. Using the Site Wide Text change I was able to change certain words, like WordPress with no problem. But when I added text changes to certain words, like "(BuddyPress)" and "WP Skills" for example the changes will not occur.

I tried certain words form the widget titles and even the complete widget title to see the effects. But nothing changes. Words in the Backend Menu is working fine. Just the Widget Titles are giving me grief.

Deactivating and reactivating plugins didn't do much either.
Any advice is welcome!

Cheers,
Ronald
