PXC Cluster Is Not Recognized Correctly When MariaDB Nodes Are Monitored

Description
It seems that if we add for example 2 MariaDB nodes which are not part of Galera cluster and 3 nodes for PXC the PXC is not correctly visible in PXC/Galera Cluster Overview dashboard. The cluster size on top is 0, although the nodes are visible in graphs below. On PXC/Galera Graphs dashboard MariaDB nodes are seen as being part of the cluster (but they are not) and when selected there's no data but when we select PXC node then data can be seen. It seems it's picking up pxc/galera cluster size from MariaDB node which is 0 there since galera cluster is not enabled in my setup.

I have a similar problem,
3 Node PXC (5.7.21 wsrep_cluster_name pxc1) with pmm-client 1.10.0
pmm-server 1.10.0
I added a 3 node mariadb galera cluster (10.2.14wsrep_cluster_name my_wsrep_cluster) with pmm-client 1.10.0
and only the mariadb one is visible in the PXC/Galera * dashboards.
pmm-admin restarts/config/add on pxc node did not help.
