I finally got my Wet Okoles in, but need help on removal of the lumbar adjustment ****.

Wet Okole told me to go ahead and cut a small hole so I can stretch the fabric over the **** and tuck behind it.

I'm afraid of cutting and then compromising the fabric by stretching it at a tear point so I'd like to remove the ****, cut and place the **** back over.

Bentley doesn't state how to properly remove it.

Anyone withy Wet Okoles w/ lumbar adjustment ***** have any tips?
