Hi<br>
I noticed you have a raster with a "minus" character in the name.<br>
Sometimes that gives trouble. Not sure if it's relevant to the current problem, but it might be worth renaming to something like "dec_juin" (underscore instead of '-') and trying again.<br>

I am working on Windows and I tried using GRASS 7.2.2, GRASS 7.4.0 and GRASS 7.4.1 to see if there is any difference, but it is always the same.<br>
