Rolling Back Issue

See [TRIM/EXTEND4] and the gap?  I created this in the "rollback" situation you see.   If i rollback anything else it goes above the rollback line why is this below the line where i don't want the feature, thus not showing what i just extended the [WELDMENT] to  in the rolled back situation. 

I need consistency SW2016 seems to have more issues than SW2014!!  

P.S. like my peagreen soupe background, easy on the eyes.. If you have a better one let me know.
