App Versioning in Helm Chart releases

[commx]

In bc14dac we have seen a version bump for the Helm Chart version (6.21.0 to 6.21.1) but a minor downgrade for the actual app version (6.10.5 to 6.8.6). That doesn't look right to me.

Can someone confirm if this is the intended behaviour?

Background: I performed an upgrade for a Rocketchat instance via Helm from 6.21.0 to 6.21.1. The retention configuration was broken (opening the Retention Policy settings always resulted in Application GUI crash; all DMs older than 1 day were pruned. After performing a rollback to Chart version 6.21.0 the Retention Policy settings worked again.
