I can reproduce it this way (GSAK 8.3.1.48):
* Start GSAK
* Run Google_Maps_V3 macro and press Stop Button
* Run Firstnn macro and select 10 caches
* Menu "Refresh cache data". Select "All in current filter" and "Full details"
=> Error "No valid caches found to refresh"
If I do the following, it works with the same 10 caches:
* Start GSAK
* Run Firstnn macro and select 10 caches
* Menu "Refresh cache data". Select "All in current filter" and "Full details"
=> Caches are refreshed
* Start GSAK
* Run Google_Maps_V3 macro and press Stop Button
* Run Firstnn macro and select 10 caches
* Menu "Refresh cache data". Select "All in current filter" and "Full details"
=> Error "No valid caches found to refresh"
