"Multiple projects" setup not working with PMA

[omcandido]

Issue I have several sites in my host machine. I use traefik to manage the routing as described here. I can browse the sites correctly, however, PhpMyAdmin is not working as expected. If I browse, say pma.site1.docker.localhost, it takes me to the pma page of another site (eg. pma.site3.docker.localhost).

I use the same .yml structure for all sites. Is there anything I'm missing in the pma settings? Can anyone reproduce this behaviour?
