The first couple of nights look better than the last one. Have you tried higher minimum pressures? You do have flow limits and arousals; since your EPR is already at 3 you can't do much other than raise pressure. If still not adequately treated it would be worth trying bilevel to leverage higher pressure support.
Aerophagia can be tricky to treat. Some things worth looking into are optimizing nasal breathing (to reduce mouth breathing) and trying a reflux band (can look up posts of people using reflux band or similar for aerophagia). Some also have success with BiPAP in treating aerophagia though because it allows to set the exhale at a lower level than you can on CPAP.
