Beam reinforcement Pin dia issue for longitudinal bars

Hi there,

I'm using ProStructures Connect Edition V.

I'm trying to place beam reinforcement with a stirrup that has one end a non-standard Pin dia. 

Once i modify this stirrup end with either a 90 degree hook with 100 mm pin dia, or a Bend with 100 mm pin dia.

it forces that corner longitudinal bar in space, it no longer is tied to the bend radius.

How can i fix this? If i try moving this bar it disappears.
