Can't complete fishing pole trap and large fish trap in coop?

So I've been enjoying Green Hell in coop with a friend. We've built a decent house in the Spirits of Amazonia map, and we figured we'd build a fish trap or two to fulfil our food needs.

• First I tried building a fishing pole trap. I can get two of the logs in the building plans, but after that it won't accept anything else. No fish hook, no sticks, no fishing pole, nothing. The only thing I can do is remove it again.

• I guess I'll try building a large fish trap instead. I place it down, we insert about 30 out of the 50 sticks... and now it won't accept any more. I can't even remove the building plans so there's a half-built trap with 30 sticks that I can't finish or deconstruct. Even hitting it with an axe won't work.

I'm kind of hesitant to try building any other fish traps because I don't want our pretty base location to be filled with white outlines that I can't ever complete or remove. Are all the fish traps this buggy? Does anyone know how to finish building either of these? Any help would be appreciated.
