Impossible to wrangle "roaming" livestock

[avancouw]

I bought a pair of donkeys from a slave trader, and immediately began building a pen. My pawn is a little scattered though and it took him a bit to get the work done - by then my donkey had already thrown a warning about wandering off the map. Donkey 1's status is listed as "roaming" and I cannot wrangle him back to the pen.

The warning the game showed me was  "Donkey 1 has started to roam away! He will leave the map unless an animal handler ropes him back to a pen."
The tooltip message is "Cannot rope donkey 1: animal busy".
I have a fenced pen with a pen marker.
Something at least very unintuitive about this design, or, something isn't working right.

Here's my savefile.
