reuploading of an overlay and incorrect error thrown

1. Not sure if it is a bug.
   In case I upload an overlay unsuccessfully (error thrown), I close error window and amend the text file data (overlay file is correct now). But, I have not closed the Add overlay window and I click choose file again to upload the file with the same name but corrected content. MINERVA does not successfully upload it, but throws the same error as before. I need to close Add overlay window and reupload file.
   It would be convenient if I could left the Add overlay window opened and choose file again.

2. Below error is thrown if I upload below overlay. The error concern the element not presented in data. If I try to upload the same overlay again, I see the same error type, but the other (map?) element is mentioned, below there is PARK7 shown, but I got also Ca2+, fibril displayed.
