Hi Dana,
There have had a few other people mention this, but haven't been able to reproduce it. Can I ask that you:
1) Open Survey123 Connect
2) Click the gear icon in the lower left (Settings page)
3) Select 'Diagnostics'
4) Enable logging and then open the file folder
5) Exit the Settings page
6) Click in the list of Surveys and drag down to refresh the survey list?
One way to solve this is to close Survey123 Connect, rename the 'My Survey Designs' folder and then open Survey123 Connect. This will create a new folder that you can then copy your survey folders into. The folders with the GUID-type names are ones that have been downloaded from your ArcGIS Online/ArcGIS Enterprise account.
