I’m having the same issue — I accidentally clicked an arrow, and now I can’t retrieve my field set from the sidebar — and attempting to change the position from the fieldset’s own edit screen has NO effect. I’m not sure what the intended functionality is supposed to be here, but it’s not working.
Any advice about how to get my fieldset back to where it’s intended to be, other than trashing it and remaking it, or disabling Gutenberg, would be very appreciated.
Thanks!
