Style > Find and Replace Text Style library and style mismatch
The names of the libraries in the dropdown do not correspond with the styles in that library. For example:

I am trying to merge local text styles with my library styles from Example_Library_1. The styles listed under the "Choose a style" dropdown are actually the styles coming from another library, Example_Library_2.

The command works properly, it just needs to be updated to reflect the proper library from the list of style options.
