How to adjust transverse bearing locations within LBC 19.01.00.11?

Hello, 

I created my model using the ABC wizard. Since this point, I have had to adjust the size of my pier cap, and now the bearing locations are off. I have attempted to adjust the locations using the Edit Bearing//Steps option but it is completely greyed out. 

Do we have an alternate way to adjust these bearing locations without using bridge parametric layout?

Sincerely, 

AY John York
