Still not sure how this happened, but I was able to modify the form in
another folder, deleting and recreating the affected controls. Seems to be
working OK now.

I made a couple of minor modifications to a custom form. Now several custom
"Percent" fields have somehow been changed to "Number" fields. The items
still hold the data (as decimals rather than percentages) but the form can't
display them as percentages.

How could this have happened? Can I change the fields back to "Percent"
fields?
