Fichier RAW importation noir et blanc Lightroom mobile

Hello,

I am new here.

here is the problem I meet on Lightroom mobile for 3 weeks 1 month.

When I want to import the photos from my iPhone taken by my SLR on Lightroom, they automatically turn into black and white and there is nothing I can do about it. Even when I want to put a color preset it shows it to me in B&W. I can't understand where it could come from. I did not change anything in my settings or inadvertently but unlikely. I tried with different Sd cards. I also specify that it is only RAW files that appears in B&W for jpeg is good. 
thank you in advance for your feedback.
