if the reason is what i think, you should be able to clear out the midi-TS if you right click the Time-signature widget, and form the context menu select remove-global-automation
You get this type of issue when you have imported a midi-file. All midi-files has a hidden Time-signature, and also a hidden BPM, so your DAW need to instructed to ignore that MIDI-value.
Besides that, since you are new in Forum
