Cyclic profile curve and UV mapping issue

Hi!

When creating UV map on profile curve and toggling the curve to cyclic, I get this one spot where the cyclic curve connects.

Does anyone know how to capture UVs here as on the rest of the profile or maybe entirely different solution for UVs here, with the result being UV map distributed evenly for all profile’s faces?
