Two sheds - still has eyecap

[Lolo76]

My 5yo normal gal Delilah sometimes has problem sheds - not sure why, since the other snakes in her rack never have an issue! She's had a stuck eyecap before, but it came off easily in the next shed. This time I waited again, but she had a second shed over the weekend and it's still there (even worse). She doesn't have much of a "film" over it, and it's not silver like the last time, but there is a white rim around the edge.

I've heard a variety of opinions on removing eyecaps, so what are your thoughts? I know tape isn't recommended by many, and mineral oil with a Q-tip is generally preferred. I've also heard of using the wet pillowcase w/ towel, but also read that can sometimes suffocate a snake (although I've done that in the past without anyone dying). I'm not exactly an EXPERT, but have been keeping snakes for about 5 years, so I am far from a newbie. Is it safe for me to attempt one of these methods myself, or should I call on a professional? Or should I wait for a THIRD shed? She is doing fine otherwise, eating and pooping/peeing as usual.

Here's how it looks right now:
