Follow not working for 1 window

Hi,
I play on retail server.
I multibox X3 , X5 and X8 team, I have a problem with /follow not working for window 2.

When I use /follow me on window 1 --> all characters follow
When I use /follow me on window 2 --> 1 character follow wrong character and other toons follow nothing
When I use /follow me on all other windows it works perpectly.

If I play with team X3 or X5 or X 8 , druids or shamans team, I always have the same problem with only window 2.

I tried to make new team with quick wizard settup with different character but I always have the issu only for window 2.

Also, I bound F11/ shift F11 / all modifers F11 ... and unbound it on all character to be sure that it's not a keybind issue.

I alsso checked My /follow FTL in isboxer which is set to F11.

I don't know what to do.

Could you healp me? any Ideas ?

Ty for your help.

There is an issue with modifiers in World of Warcraft at the moment. Left and Right Modifiers are not being differentiated so FTL used with Follow and Assist do not work. In a team of 10, slots 2, 7 and 8 are affected.

If you are 5 or less, you can update slot 2 FTL modifier like this. You have to /reload ingame after export.

You can only use FTL up to 7 slots now. This is the 7 possible combinations you can use.

This is a WoW Client change and not something that is directly related to isboxer so we'll have to wait and see if it gets changed back.
