After exporting, cannot play back with ardour;

After exporting a track with Ardour, I can’t play the track anymore. The Auto Play and Auto return buttons are both selected and cannot be de-selected:

Any ideas?

What version of Ardour?


@Seablade: 2.8.11. Sorry for the omission.

@Boesman: Thanks. I had to run out of town yesterday, but I’ll test it when I get home tomorrow.
