"Import To" Missing Actions/Sub-menus

I notice two issues

One, the import screen despite being selected as COPY, looks more like ADD. Perhaps your preference file is corrupt and needs to be reset.

The preference file can get corrupted, leading to all sorts of odd behavior. Resetting the preference file is basically deleting the preference file (or relocating), and restarting LrC, whereupon LrC will recreate the preferences file. The preference file keeps track of all sorts of things, not just the preferences settings. Note that a side effect of doing this may/will return preference settings to defaults. Carefully read the following references.

It's recommended to backup your preferences before you reset the preferences to the default settings:

Second, I suspect you use an MS account, not a local account for logginig on to yur Widows computer. As such several System Folders (Librarys) are associated with OneDrive. Typically auto sync to OneDrive. Folderrs like Pictures, Desktop, Downlaods, Videos. I suspect if upi bring up LrC /Help/system Info/ you will see a Libary path that includes OneDrive in the path. THis can be bad. This can effect performance. Blame this on Microsoft. Typicall sollution is to create one or more folders of your chossing and move your catalog, and in your case, the photos, to. Something like MyPhotogrppapy, Lightroom, MyPhotos, Rumplestilsikin, any thong other than Pictures.

Oh, you can use OneDrive to Sync, just Sync while not actually editing in LrC. Or Sync outside of LrC. And do not conflate the use of OneDrive with proper backups, it is not.

Right click one of the other panel headers, like File handling or Apply during import.

Then choose the panels you want to display from the context menu.
