Hello,

Incremental saving can often cause issues with multiple signatures. Check if you’re using the incremental saving mode and if so, changing it to REMOVE_UNUSED. See the following post for more info:

If this does not solve your problem, please send me the following information:

  1. Input file(s)
  2. Generated output file(s)
  3. Code and settings used to generate (2) from (1)
  4. Screenshots showing the output, and clearly indicating what you expected to get instead, and also clearly indicating the application/browser being used to view.
