Why does this change?

[Nintendo-Daily]

I use the ibproarcade modification for arcade games. For each arcade game I have descriptions of the game. For some reason I get the following when I type a description for games that I add.

For example, I want this:
"Destroy groups of 2 or more bubbles to get points. You lose the game when there are no more bubbles to destroy."

But when I save it, it look like this:
"Destroy usergroup of 2 or more bubbles to get points. You lose the game when there are no more bubbles to destroy."

It appears that the work "groups" is getting replaced with "usergroup" some how.

I looked in my replacement variables option and I don't have anything set there that would affect this.

Any ideas guys?
