Loft only knows how to cap planar ends to make a solid in addition to making the "side walls". After using the Flow command your curves are not planar and so they aren't getting planar end caps put on them.

The easiest way to solve this is to make your text into solids before you do the flow and apply the flow to the solids instead of to curves like you have done here.
