Multisite & wplms

Hello and first really thanks for your plug in ! I’m currently building my website multilingual with a multisite setup and your plug in is a great help ! It’s working almost perfectly, everything is well redirected when changing language…
but I still have one issue with one wplms page:
The page course is the archive of all lesson, on the two versions and well linked one to the other..
one is in english /courses and the second one is in french /cours

changing language with your plugin from english to french it finds the good url, but from french to english it does a mistake and choose a wrong page…
I guess it’s because the course page is special but is there anyway that I could fix this ?
maybe add manually on my template something like :
if page==”cours” and language==”fr” { $englishUrl=”/courses/” }

thanks for any help !!
