How to get Time zone in MIDI Editor (Key and Drum) back to bars and beats?

Somehow the time format in the Drum Editor (and Key Editor) is displayed in minutes and seconds. It used to be like the rest of the project in bars and beats.
I don’t know how this happened and I can’t find a solution to fix it.

I’ve included a link to a screenshot Time Format in drum editor


Click to the arrow in the midst right side of the Key Editor’s ruler and change it. Or set the Primary Time to the Bars+Beats.

Thanks for the reply.
Because of an hardware error I had to reinstall my system, so I didn’t have a chance to try this.
