Hedgerow bug?

[BigDuke66]

Just played scenario 88 and saw that hex 37,34 & 16,37 had hedgerow graphics but were listed as clear in the top bar.

Tried now the map editor and the end hex you set for a hedgerow line is always listed as clear, tried making a trench line and that works, second hex is a trench too.

I'm playing version 7.
