Strange issue with boundary patches - Gaps in edges

Sailed the seas of google and tried alternate methods for hours. boundary patch will create the surface i'm looking for, but there are tiny gaps between the edge of the actual boundary patch and the 3D sketch used when patching. it's most visible when two boundary patches border each other.

I'm making sure to use the 3D sketch as patching references and not previous boundary patches

I tried to create a similar surface with surface lofts but it doesn't give me the shape i'm looking for. Surface patch always gives me what i'm looking for but alas, problems arise.

I've attached my file and a picture of this gap.
