GUID id printing instead of Text for Dynamic value "Responses Comments"

[pavanrspl]

I have two different stages, in one stage responses comments are printing with text but in another stage it printing guid id.

When I hover the cursor over the dynamic content of the one whose GUID is to be printed, what kind of string is displayed? Are they both the same?
Also, when the GUID is displayed, what string is entered in the actual approver's comments
