"Enter" bring up buttons

Ever since the Facepunch update this forced wipe, I am having several players complain that that when they hit the Enter key to bring up in-game chat or enter a code in a code lock, etc. it is bringing up the command associated with one of the Individual Server Buttons at the same time.

For example, I have Individual Server Buttons that do /clan and /players and both of these will pop up when they hit Enter. So the in-game chat will show, but so will the clans menu or the player list.

I have tested it by changing the command on the button and when they hit Enter the new command is launched, so it is definitely XFastButtons that is getting triggered. 

It does not happen every single time they press Enter, but it happens frequently.
