Cannot remove widgets

Fenix 5s
While exploring new widgets with the garmin connect app I noticed that as well as the default ABC widget which has compass, altimeter and barometer screens there are also three separate widgets for each of those. I added them to check if they had any extra information on them, discovered they didn't and now want to remove them, but can't! I get an error message on the Connect app, and they are adding three extra key presses to scroll through the list.
It's not a major problem, but is a nuisance and a peculiar restriction of not possible.
Has anyone any ideas about how to remove them? Would a factory reset bin them?
