I can reproduce with the charmed-kubernetes-485 bundle and upgrading the kubernetes-master or kubernetes-worker charms.
I cannot reproduce with a local lxd profile test charm. Including the charm upgrade part. Nor can I reproduce with the cs:~juju-qa/bionic/lxd-profile-subordinate charm. I started with revision 0 and upgraded to the current revision, 2.
Confirmed.
