I decided to re-install WinSCP. After installing, I imported the configuration. Most sites were lost. The 13 sites that were lost were in a folder.
1. I exported the configuration. Site Manager-->Tools-->Export/Backup Configuration
2. Re-installed WinSCP from the Windows Store.
3. Imported configuration from Step #1. Site Manager--Tools-->Import/Restore Configuration
Were you using Store installation before the reinstall? Can you see the lost sites in the INI file? Can you share the (anonymized) INI file? Is the screenshot from before the reinstallation? Or what does it show?
Yes, previous installation was from the store. The screenshot is from after the reinstall. The sites were indeed in the INI file. I have since rebooted and the sites returned (thank goodness). However, some sites did not return under the original folders. I'm Ok with this. I consider this a win :)
