Adobe Acrobat Reader

Hello everyone;

I am using Adobe acrobat reader on an iPad/iPhone

For about the last couple of months have been having an issue moving files. Working on my local folder, I have a document created  that I need to move to a folder that I have already created.  First I click on the checkmark in the upper right-hand corner, second I select the document that I want to move, third I go to the bottom of the screen and select the move box I then get a choice to either move or duplicate and I choose move, next a window opens with the list of my folders that are in my local folder. Prior to a couple of months ago that list was in numeric and alphabetical order, but a couple of months ago all of a sudden there’s no order to the list meaning each time I move a document to a folder I have to scroll through the list looking at each file out of hundreds to find the one I want to move the document to. Please someone tell me what happened  and how to fix it. I cannot continue to search through a list of disorganized folders every time I want to move a document. Thank you for everyone’s help. PS every time I try to find customer service for adobe I get the runaround, if  someone knows how to communicate with Adobe customer care for adobe acrobat reader free version please tell me.
