Wingtip deforming at cruise, guessing there’s a stiffener missing?

Gotcha. Yes, from the plans I can now see that the factory parts are there. The article tips for tips shows using additional reinforcement via dowel rods glassed in which seems like the way to go.
Random thought; has anyone considered using spray foam? You would have to leave space for it to expand outwards and not top to bottom to prevent distorting the tips...

So Brent and I are helping on the same RV-8.
The wing tip rib is missing on this build (each side). I guess the builder never installed them. Move the aileron out of the way and it is an open void in the wingtip. This is allowing the deformation. I was going to order the parts today.
Without having built, or having plans in hand I?m not sure what to order. W-412 one wing tip rib I?m relatively certain is missing. My question is do I need 2 of these one for left one right? Or is there a different part number? I imagine a different part # since I don?t believe they are symmetrical. The parts person at Vans didn?t know.
Thanks
