I am just doing shrinkwrap title by placing InDesign document into another InDesign document While perfoming this my font count keep on increasing its a nature of InDesign or there is any way to fix it. I attached screenshot for your reference. It shows duplicate font. For each and every page it count the same font name.
Nothing to fix; This is normal behavior. Your imported file is being placed as separate graphics files, so the list is showing what fonts each of those pages requires. The alerts are indicating either that font is missing or some other error. (My guess is, if you placed your imported file into a new document that is not currently using those fonts and they are not currently activated, the error is likely that the font is missing.)
If you load those fonts, the error should go away, but the list will remain, as it should.
