Limb shift tech shifting

Has anyone had or have heard of there limb shifts moving? I’ve shoot around 1,100 arrows since I tuned my bow using limb shift

I did tighten the locks appropriately

The bottom cam shifted about 2 turns to the right

I retuned and took photos of the limb tech marks and marked them with sharpie. I’ll monitor if they shift again after a month or so of shooting
