We upgraded to 0.34.2 yesterday and are seeing empty dd.env and dd.version values set in our telemetry.

An example log is here:

[dd.trace_id=1418951474465141154 dd.span_id=7662676986696068047 dd.env= dd.version=] 
<log content>

The addition of these values broke our grok processors. We do not have dd.env or dd.version environment variables, nor are we setting it in the tracer config. We are setting the env via tags like so:
DD_TAGS: "service:api,env:<%= env %>".
