Light Welding regeneration error in drawing

I used a fillet light welding feature to weld two pipes in perpendicular. The feature is not failing in the assembly while regeneration but the feature is failing in the drawing but when i open the assembly again it is fine the problem is only in the drawing. I have also reduced the light welding curve thickness to 0.000 in the welding preferences for the fillet welding and all the other welding.
