Heavy layer line with transparent PLA and curved protrusion

I’m printing the lid for a container using transparent PLA and Bambu’s recommended settings for transparent PLA. Overall it was working well, until I added a handle to the lid. Now, the layer where the handle ends is printing much heavier and a bit uneven vs. the other layers. I’ve played a bit with the seam settings but it hasn’t helped (and I’m a bit of a novice here).

I’m attaching a screenshot of the model from Fusion, along with photos of two print attempts.

Any ideas?

Thanks!
