Ok, so I wanted to be sure that those tabs were actually touching the fabric on the top, so I put some baby powder on the tab and put black duct tape on the fabric side to protect the fabric a bit. When I put the top down and then back up, I saw the baby powder right on the black tape, which proves the tab is what is pressing into the fabric. I left them there for now cause I'm sure there's a reason for them to be there (perhaps to stop one of the frame ribs from moving further back when the top is retracted)? Hoping the tape delays the top from ripping for now.
