Short passing, a gap in midfield and 5 advanced players. Your team probably isnt producing the right kind of opportunities like that. At some points you are going to have 4 players in the box all vying for the same opportunities.
Advanced or complete forward might help, shift one or both AP back to midfield. Possibly make one a CM or DLP.
I rarely use limited defenders above league 2 level as they just lump the ball forward and often lose it, and with nobody really in the middle of the park it just invites pressure for you, hence late equalisers.
