Thank you very much for the question!
This is another defect in our system, registered as DEF-5363. What happened in your case is that: when we use the arrow style, with a dimension that is too small, the arrows are too close to each other, therefore the program can't draw the two arrows in this place. The code can't handle this situation, and can't draw any arrow after this point on this dimension.
At the moment, we are still working on a solution for this issue. Unfortunately, there is no other workaround than using a smaller arrow, or changing to a different dimension marker.
I'm very sorry for the inconvenience! Feel free to ask if you have any further questions!
