The ends of the beam reference lines look like they join so the beams should trim to an apex - they do when I model them.
But it looks as if you have something else cutting the bottom of the beams - maybe that is interfering with the connection?
Drag a copy of just the 2 beams away and then see if they trim.
If not select them in plan then FILE menu > External Content > Save selection as module.
Zip that .MOD file and attach it to the post here.
