Attachments bug

Hi,

For the last couple versions of RDM I've been experiencing a bug when I save multiple files as attachments to an entry. The files will attach OK but no matter which file I select to 'Save As', only the first file that has been attached is saved. The file name and extension are correct when saving, but the file size and content are equal to the first attached file and not the selected file.

I have to delete the first file to get the second file, and have to delete the second file to get the third file. I've tested using different files and file types and multiple entries with the same results.

I was on RDM 11.0.18.0 and just tried 11.0.20.0. Windows 10 64 bit.
