You’re right. This is a significant issue. I’m surprised that this hasn’t come up sooner. Thank you for your persistence.
The glitch with drop down forms on both pages will be fixed in the next release. But for now, please open /osta/inc/staff-foot.html and change line 42 from
$("select:not(#timezone-dropdown):not(select#user-name):not(select#cc_users_open)").select2({
to
$("select:not(#access select):not(tbody#rules):not(.filters-page select):not(select[name^=\"rules\"]):not(#timezone-dropdown):not(select#user-name):not(select#cc_users_open)").select2({
And if you come across any other glitchy drop-down lists please do not hesitate to let me know.
