damn!( I made a copy of list for temporary reason and deleted it (list, forms, elements without dropping database). Now it doesn't show elements of one group in a original form of original list! I've checked, these elements still exists and, but there are changes in their Full Element Name - added "40_repeat" in its middle, for example it was "fab_zayavka_new_zayavka_online_payments" and now it is "fab_zayavka_new_40_repeat___zayavka_online_payments". When I try to make new element it also add ""40_repeat" to the name of new element, and also doesn't show them in a Form. I've checked the name of database in a list paramentres - it's still the same - "fab_zayavka_new". I'd like to see my elements in a Form, anybody know how to solve this problem? or I should make new list and all elements again from zero point just because I used copying of the list?
