Hotkey for changing chat tab always skips two tabs

Hey everyone,

Usually I use Ctrl+PgUp/PgDn to switch between chat channels. As of lately, doing so always brings me three tabs to the left/right.

Example:
Main chat, Channel Dragon, Channel Marketplace, Channel German.

When I'm in the Main chat and press Ctrl+PgDn, the chat switches to the Channel German instead to the Channel Dragon.
Pressing Ctrl+PgDn again brings me into the Channel Marketplace (skipping Main chat and Channel Dragon).

sounds like the ctrl+PgDn is moving you BACK on channel. if your on marketplace does pressing ctrl+PgDn move you to dragon channel?

Yes, it is doing this in both ways, forwards and backwards. Ctrl+PgUp moves three tabs to the left, Ctrl+PgDn moves three tabs to the right.
