Spire.PDF: An item with the same key has already been added

[VolodymyrKhrushch]

Good morning E-Iceblue team!

I've encountered the problem with your Spire.Pdf.SaveToFile method from Spire.PDF library which falls into exception: "An item with the same key has already been added". It happens with only few of our documents, but happens constantly. I've found out already that this exception pops up quite frequently in other libraries, like Spire.XLS (topic "Exception: An item with the same key has already been added"), and even in the same Spire.PDF earlier (topic: "Getting exception "An item with the same key has already..."")(I can't post links). I can see that some of those cases you were able to solve on your side. Do you have any ideas how it can be solved in my case? I'd be very thankful for your support. I'm using Spire.PDF library version 6.8.5.
