Why does the force duration button keep turning itself off?

This is new since the last update. I rely on it to make sure I get dotted note values instead of tied equivalents, which happens a lot.

Dear Richard,
I do not understand your question… Since last update, it is possible to apply force duration to an existing note, thus “freezing” its appearance. If you navigate between notes that have received that treatment and notes that have not, you might notice that the G-clamp lights on and off, according to the force duration status of the note. This is all expected behavior (read Version history).
You should notice that, in Note entry mode, if you enable force duration, it should remain on until you press o again to turn it off.
Is there anything in what you see that is not described in this post?

I’ll just quote myself:
