They didn't directly, Carlos just changed "Gundam Build Divers" to "Build Divers", it's the Lua script behind the categories that tagged it when it saw something compatible.

As for the Fighters/Divers issue, while neither show give any concise landmarks as to when they take place independently (a year or "timeline" is never outright mentioned), there is clear sign that Divers and Fighters share some kind of overlap (GP Duel technology heavily resembling the Gunpla Battle system, and custom Fighters MS appearing in Divers). As a result until proven otherwise, it is accepted that the two are probably taking place in the same universe, but Fighters came first, so it gets top billing.
