HELP! Selector doesn't work more in Adobe

i just completed my robot which performs a data scraping of some invoice invoice fields in adobe acrobat reader versione Schermata 2022-01-05 alle 00.55.13
The strange thing is that it worked before but now the robot no longer finds the fields, in fact if I try to select them again with “find element” I can select only the whole document and not the specific fields.
What could be the problem @Forum_Staff ?
TKS you in advance guys

Thanks so much
