Microstation U14 does not show existing Tags

I have Files, where U14 german does not show Tags, this is confirmed for several Files and Installations from my collegues.

The same Files worked with older Versions like SS10.

SR is on the way - we really need a version 14.1 for this bug, waiting for U15 is completely unacceptable !

The problem may be related with the Tag Range of these Elements, if I add new Tags in the same Files everything seems to work OK.
