Local check on windows not being picked up

I don’t know. it’s a simple one line script. This is the entire thing:

sqlcmd -S . -E -Q "exec DBA.dbo.prcDBAcheckMK_BackupCheck"

the procedure returns multiple lines, which is in the exact same output as a bash script we use to check our Postgres backups. If I change it to a .bat file it still doesn’t work, either.
