Hi Dominique,
Thanks for your answer 
I’m using the last version of Lt on openoffice and the Lt’s website.
They are saying the same thing:
Its the same when I’m writing “An sm-mañ a gasas un sms din”, and a lot of words with a “gostly” vowel like it.
Others exemples:
An FNSEA
An FDSEA
An FN
…
So and so 
I’ll send you some words I think in a few days
