14k yellow gold ring bent after two weeks

[Morelandsara4]

Is this normal? Two weeks seems quick to have this happen. I don't wear it while working out, I take it off while doing anything with my hands like washing dishes etc, and I don't use my hands in any strenuous way for work. When my fiancé gave me the ring two weeks ago I wasn't able to see where it had been resized, but now it's obvious. I know that this happens over time, especially with a thin band, but two weeks seems too fast? It was actually more warped than in this picture and I was able to pull it out a little bit with just my fingers. Is it just the design of the setting? Can resizing cause this?
It makes me nervous that the prongs are soft?

It does seem very unusual that a plain band would get bent so far out of shape so quickly without you noticing something adding pressure to your hand. I'd take it back to the jeweler and have them check it out. If the ring was cast maybe there's a porosity issue with the metal? No idea but you're right, this shouldn't have happened within two weeks and I doubt you've, like, forgotten slamming your hand in something or whatever.

What is the thickness and height of the band there at the back?

Thank you! The jeweler emailed me back. If I send it back to him he'll fix it, but I'm nervous that it's just going to happen again quickly. He is going to call me today to discuss why it's happening. I'd like to be prepared with the right questions.
The band at the bottom is just under 2mm thick and about 1.5mm high. Is that just too thin for 14k? Would the knife edge contribute to it being more malleable?
