http://www.fixtradingcommunity.org/pg/group-types/member-firm-groups suddenly shows me not only as a member of Deutsche Börse Group but also Market Prizm Group which supposedly has just one member. The group itself does not show me anymore and the swipe menu allows me to ask to join the group, i.e. it knows I am actually not a member. Please check the inconsistency. I raise this here as it may be an issue that is not specific to me.
Sorted. Someone added you in error when setting it up! human error
