Error with group lvl

i have made a group since long ago and have been in my own group since then ... recently the group lvl has been bugged. i'm a lvl 38 and the group been showing lvl 39 , which is impossible because as a leader of the group you cannot invite someone higher lvl then urself. while it dident bother me that much as i tough once i lvl up it would fix itself. I log in today and the group of the lvl has changed to lvl 40 ? really ??? how is that piossible ? plz look into this and fix it to its proper lvl as disbaning the group and recreating isent an option with all the gear i got in the backpack.
It's possible that someone who was in your group during it's time is higher level than you now, if you wish group level to be reset you'll have to disband it and recreate.
Some information is still stored (similar how you cant join Duel if you've had opposite faction members in your group even though they already left it)
also randomly got this msg... we were doin lvl 37 elite
1:14 Heaven's Voice: Instance Razed Fort has been disbanded.
how can some1 who hasent been in group for days now still affect my group ?
