Can't import database

Hello, I exported an YaCy index as XML in tc.gz

The new version is docker, and the previous wasn’t. I put it in:
/srv/yacy/yacy_search_server_data/SURROGATES/in/

Then imported with the “Restore” function. It said success, but…
While it’s showing up on the panel for total space used by yacy, but not showing up in the index.

regardles of discussion in Exporting Index from Unstable to Stable :

i wonder, if that couldn’t be connected with this recently fixed bug, related to json export/import?

just guessing…

debug messages from the log could tell more…
