Convergence problem due to meshing one area

I'm doing 2D paraglider airfoil simulation and I have some convergence problem due to meshing.
As you guess, paraglider's leading edge is open in order to fill the air inside and inflate the paraglider.
I use y+ = 1 and use spalart allmaras or SST-Kw model. I even try the RSM model.
When I'm meshing, I mesh outside and the inside of the paraglider, as you can see in the attachment "1".
BUT! I can not make it converged. It oscillates.
I wondered and tried to close the leading edge, to act it like a normal airfoil, As you can see in the attachment "2". Then, it converged easily.
So, I wonder why It doesn't converges when I opened the leading edge and mesh in it too. I use same methodology in 2 cases.
Thank you for your answers.
