Maintain material specification: Caracteristic assignment (QM)

hello,

When I use the Tcode (QS61) to assign a "Qualitative" characteristic, all the qualitative characteristics aren't displayed in the table (picture QM), however, this isn't the case for the "Quantitative" Characteristics. You can see the picture attached below.

Quantitative characteristics: PH-chocolat, viscosité, poidschocolatchaud, as you can see are mentioned in the table,

the qualitative characteristic (picture QM2) that i have created (CL01) isn't displayed here. Help please
