Generative Remove does not complete brush stroke before it begins "analyzing"

I'm new to Lightroom and just started using Generative AI. It was going great at first, I was able to successfully remove cars, signs - then it started behaving strangely and not working properly. I have Generative AI and Object Detect checked.

Basically the behavior is this, when I start drawing a mask, instead of rendering a red mask I get a white outline of the brush stroke instead. It won't even allow me to continue along the entire object (in this case a power line), it just stops and then I get a black 'Analyzing' box. After that's done, the white outline transforms into a red mask - but it's much larger than my original brush stroke and very boxy. I tried to continue with my brush stroke along the object, it drew properly for awhile after that but it would delete the last portion on its own. I tried several times to redraw this last portion, but it deleted it every time. This last portion was the power line coming in front of a house, before that the sky was behind the power line. I then hit enter to see what would happen, to see if it would actually remove the object, but it didn't. The shape of it was changed somewhat, that's it. I tried the variations and none of them removed the power line either.

I have tried it with other objects, such as a garbage can, but I get the same problem.
