Problem with entering chord symbols

Entering chord symbols using the MIDI keyboard does not work. Using the Shift-Q shortcut, a popover appears, but I cannot enter a chord using the keyboard. If I enter it in writing, for example Bb, the chord will save it. I’ve been working on Dorico since the very beginning, but I’ve never had this problem. Please advise!

Have you checked this Note Input Option? (Ctrl+Shift+I)

Yes, I did that. Normal note input works

I tried this function-chord entry-in Sibelius and it worked there. I closed Sibelius, opened Dorico and suddenly it worked !!! Interestingly…
