HTTP 206 response when enabling mod_deflate

Hello,
I'm struggling with my reverse proxy setup using apache.
        Apache does the TLS termination and forwards the requests to a
        dotnet core service on localhost. The service responds to all
        requests with HTTP 200 (verified using tcpdump) but with "
Transfer-Encoding: chunked".

If I enable the option
          "AddOutputFilterByType DEFLATE application/json" in apache,
          the forwarded response gets compressed but sometimes (not for
          every requests) changes to HTTP 206 (partial content). This
          does not happen if the option is not set.
Could this be a configuration error on my
          side or is it a bug in Apache, mod_deflate or mod_proxy?

I'm running an apache 2.4.33 on Ubuntu 18.04

        Please let me know if you need further information.

Thanks for your help.

        René
