Playback Options wont open

[Tranter]

Have some error with opening "Playback Options". Everything works nicely after starting the system and using it first but after some time it stops working for some playbacks. Opens just the empty sidebar:
Have got the problem on Quartz, also with Titan Mobile and on Titan Wing playbacks. All systems are running v10.1. After restarting the Titan software it all works again. Some bug or just some mistake by me?

It looks to me like there is a '.' in the search field. Try pressing backspace or del to clear this.

Somehow I make the "." into field yeah. Thanks for pointing to this
