Newbie full local windows stack loki not escaping windows \ paths

I am new to PGL but have a full local windows install. (no linux, no docker) .
Scraping some log files with Promtail and all seems to be processed ok…
But when I explore the log labels -> Filenames or drill down I get into trouble with the \ in file paths.
So clicking any log file will get me the Parse error…
Manually adjusting the query and replacing all \ with \ works, but just for that file and when drilling down the windows paths keep popping up.
Is there a way to prevent this from happening ? Is it a setting in Loki or must this be fixed in promtail ?


I have exact same problem with log files scraped from the Windows machines.
Loki and Grafana is actually run at Linux side.
