TIFF exif issue

I’ve used this:
How to clean exif data in tiff image|Documentation (aspose.com)

My image was taken with a Canon DSLR with CR2 extension, I opened it in Photoshop and saved as TIFF, then used the above code on this TIFF file and the below 4 exif tags were not removed using Aspose:

Date taken


@australian.dev.nerds, thank you for your contact.
I checked in my case, tags, Authors, Date taken, Copyright are cleared.
Sorry, but i don’t understand what the Byline tag means.
So that I can figure it out, could you provide the source file, tell me the version of the Aspose Imaging library you are using and the operating system, and tell me how do you check tags?
Thank you!
