Are you using repeats created with the repeats - ending dialog or the built in BIAB 3 repeat default?

In the dialog, you may have to "edit list" (bottom left corner of the first popup box) first.
If it's the BIAB default the change the 3 to 1 to the right of the style info


BIAB for Windows Version 2019 (643)
