Acrobat renaming PDF files, and changes the names entirely.

Hello,

I work for a company where mulitple people access PDF files in Acrobat. This issue is happening for about a month. When a file is open (in an open job folder) on an iPad, edited, saved and about to be emailed; the file name changes to another file name (in a completed job folder). For example. The open job file name is: 0000000_1234_MainStreet_Chicago.pdf and gets changed to 0000000_5678_SecondSt_Naperville (Conflict).pdf. The content of the PDF is not affected, just the name. The conflict name is an old job file name that is usually weeks old.

We are using Acrobat Reader APP (the files are in Dropbox) on Apple iPads. Files also are accessed by a MacBook, Apple mini, and ThinkPad. Any help in fixing this problem would be appeciated.
