Simple. X-Men Timeline:

X-Men: First Class happens X-Men Origins: Wolverine happens X-Men happens X2: X-Men United happpens X-Men: The Last Stand happens The Wolverine happens X-Men: Days of Future Past (future part) happens

Wolverine gets sent back in time, thus creating new timeline where:

X-Men: First Class happens X-Men: Days of Future Past (past part) happens X-Men: Apocalypse (thus, deleting all of the X-Men movies except First Class)

Hope that kind of made sense
