My layer/color change won't sticking together

I’m at the very top of the print. And this edge won’t stick. I tried twice. The R and the rest of the name does stick well though. I stuck a screwdriver under the layer to show the layer isn’t sticking. That dark brown is supposed to go outline the bear.

What filament are the two colors?

Enable beam interlocking in Bambu Studio. Check the preview, it should show the second color extending into the main body.

Hi, I’m using PLA. Wait…I found something.

Is that layer I’m having trouble with floating in the air? That stack of layers on the right side seems to be attached to the light brown, but the dark brown outline is floating?

beam interlocking doesn’t make it better either.

Is bambustudio complaining about the model being nonmanifold + need repair?

Is the geometry of that gap like, a super thin wall, holding up that 2-wall-wide top? Too thin and the slicer ignores it - you can enable arachne wall generator and use smaller minimum feature sizes if this is the case, to try to coax the wall into printing.

Thats all i got.
