On my site, I have permalinks for different categories. If I have a forum with the same name as one of the categories, then the permalink for that forum will have a “-2” added at the end. For example, if I have a travel category and a travel forum, then my travel category will have permalink:

Here, I changed the Forum slug in the backend to “cat” instead of “forum”.
Why would the forum permalink add a “-2” at the end? Every time I try to update the slug to the forum from the backend, just adding “travel”, when I save it, it comes back to me as “travel-2”. This one has me stumped.
