Unsure of brand but my flexifoils have a double layer around valves which ruffle up
Also if your valves aren't set correct ie twisted clock or anti clockwise this can cause a similar appearance,
Can get seriously frustrating as the winds rattling the front door and howling through the window

Have you tried putting a bit more into it, not fully as this can also pop out a snag , generally when you see this you stop putting a bit more air in , a bit of a massage along the le in said area can help align everything
