Logged in as Master admin
In left menu, select Virtualmin
In Virtualmin left frame, select domain2
In Virtualmin left frame, bottom of frame, click on "System Information"
In right frame, System Information > New Virtualmin Features shows "Let's Encrypt improvements | Try it ...
Click on "Try It ..."

Expected result:
Right frame page title "Manage SSL Certificate", subtitle says "in doman domain2"

Actual result
Right frame page title "Manage SSL Certificate", subtitle says "in domainX"
where "domainX" is some other virtualmin domain
In virtualmin left frame, domain selected changes to domainX

No immediately obvious way to get to Manage SSL Certificate for domain2
