After upgrading Linux client to Version 6.4.0 (471), I now see numbers after name of each person

[callen9292]

Hi, I upgraded to the most recent client version for Debian Linux and now in the meeting view, after each person's name I see this additional piece of information that follows a <integer>@<integer> format. Some examples are:

144@8

144@-1

360@22

240@-1

144@9

Is anyone else seeing this or knows what it is?
