All punctuation such as exclamation points, and question marks are going to the beginning of sentences. I tried to find some solutions but there are no such topics for Premire Pro. The only thing I found is to set up - Edit>Preferences>Graphics and check "European and East Asian" but this didn't help.
If that doesn't work, try resetting the Workspaces: Reset a workspace Reset the current workspace to return to its original, saved layout of panels. 1. Do one of the following: • Click the Workspace menu icon and select Reset to Saved Layout. • Choose Window > Workspace > Reset to Saved Layout. from here: https://helpx.adobe.com/premiere-pro/using/workspaces.html
If that doesn't work, try creating a new project and import the old one into it.
