Put on new Falken Wilpeaks AT4’s and they needed rebalancing after a month. Is this normal or okay? These weights were not visible when they were first installed…

Had new tires put on about a month ago at discount tire. Noticed a very slight wheel bearing noise in the rear when coasting at low speed and I had wheel wobble at about 60mph. So I went in today and had them “check” it out and they “rebalanced” and found nothing that was causing the noise. So I left and when I got back I noticed the weights like a slap in the face and also the adhesive. This doesn’t seem right…I never noticed the weights at all when they first installed the tires. Also just fyi, the bearing noise is still there and the wheel wobble is still there lol. It’s my first 5th Gen with matte black. Something seems off with this service. Thoughts? Thanks!
