Custom parameters' description not showing in QGC


I’ve added custom parameters to the software for a custom module I’m building, and while the parameters do appear in QGC when the module is running and seem to work fine, I’m not getting the description, unit nor the min/max values in QGC. Is there any step I missed ?

I followed the metadata procedure from Parameters & Configs · PX4 Developer Guide and the parameters.xml generated file does have the description fields correctly filled, example :

<parameter name="MYMOD_R_T" default="0.3" type="FLOAT">
      <short_desc>Roll failure trigger time</short_desc>
      <long_desc>Seconds (decimal) that roll has to exceed MYMOD_R before being considered as a failure.</long_desc>
