Sequence always stops after 5 seconds

I have a 15 seconds long sequencer animation, a camera flythrough, which stops after 5 seconds no matter what I do. Plays fine while editing but as soon as I start it in game, from the level blueprint, it never plays longer. If the sequence is shorter (like 2 seconds) then it ends at the right time.

The camera cuts track needed to be adjusted when the length of the sequence changed…
