vba DocID change every time I reopen file

In some Corel files, first and second open times give me different Metadata.DocID. It change every time I reopen file. I didn't change anything in file.

But some files I copied from another computer didn't happen. It's still the same DocID

Can I make it stop changing in app settings? I need DocID for identification instead of using file path or FileInfo.

Thanks everyone!
