Extension BLF's not working after update

Was running, and updated to the current last night. Using Aastra 6700 endpoints

Today, the extension BLF’s on the add-on modules are all showing question marks - the speedial part of the button works, however the BLF doesnt.

The hints/blfs work for other features like call flow control.

Also, when performing the upgrade, it appears the update enabled my disabled DAHDI module, and killed my manual PRI settings.

If there’s any particular log that would help, I can post that up.

Thanks in advance

Just to update in case someone else runs into this…

Using Asterisk 11.23.1 and Aastra 6737i firmware

Reverted to older firmware and issue cleared
