i have signed a PDF document in Acrobat. It was save in the app itself and i can't delete it. it is a P&C document and it is not making sense that user can't remove the agreement

it is not safe to use adobe acrobat to sign an important document.
i talked to the customer supoort and was told it is impossible to remove it.

the only way is to hide it which is kinda ridiculous.

please help and improve.
