Hello,
In the recommendations for the Fingerposts Fast Travel mod, the author indicates that the Atlas Map Markers plugin should be loaded first.
Currently, Loot places Fingerposts Fast Travel quite high in the plugin order. At the very bottom are Water for ENB, then Atlas Map Markers.

Two solutions:
Either manually move Atlas Map Markers up before Fingerposts Fast Travel.
Or manually move Fingerposts Fast Travel down after Atlas Map Markers. However, in this case, Fingerposts Fast Travel conflicts with Water for ENB, and color breaks may be visible in the water near Whiterun.
