Acrobat Pro deleting random letters and adding double space between words
Apologies if this error has been answered elsewhere; have not been able to find any mention.
The Edit PDF module is deleting random letters throughout the document - mostly "r" and "e" and showing a double space before the next word.

When the double space is deleted, the missing letter can be re-entered but the double space before the next word remains.

Format Settings (in the right-hand sidebar) do not seem to change between affected text and other text in the same pargraph.
Any suggestions on what's going on and how to correct this would be very welcome.
Thanks,
Dennison
