InfluxDB subquery no longer supported in >= 6.1.4?

I have grafana 6.1.4 and Im using the influx DB plugin and am trying to write a sub query. If I switch to the query inspector, I can see my query return values, but anytime I try and save it, the query editor mode changes the query and gets rid of of the first select.

Its like the old raw mode doesn’t persist.

Is this expected/known behavior?
