rasdaemon dimm label format / sysfs content missing

[dgcampea]

Labels don't seem to be correctly applied when using rasdaemon.
If I edit /etc/edac/labels.db and add:

Vendor: ASRock
    Model: X99M Killer
        DDR4_A1: 0.0.0;
        DDR4_B1: 0.0.1;
        DDR4_C1: 0.0.2;
        DDR4_D1: 0.0.3;

edac-ctl seems to detect the correct sysfs dimm directories:

# edac-ctl --print-labels
LOCATION                            CONFIGURED LABEL     SYSFS CONTENTS      
mc0/csrow0/ch0_dimm_label           DDR4_A1              CPU_SrcID#0_Ha#0_Chan#0_DIMM#0
mc0/csrow0/ch1_dimm_label           DDR4_B1              CPU_SrcID#0_Ha#0_Chan#1_DIMM#0
mc0/csrow0/ch2_dimm_label           DDR4_C1              CPU_SrcID#0_Ha#0_Chan#2_DIMM#0
mc0/csrow0/ch3_dimm_label           DDR4_D1              CPU_SrcID#0_Ha#0_Chan#3_DIMM#0

But doing the same for rasdaemon by adding the same content I added in /etc/edac/labels.db to /etc/ras/dimm_labels.d/asrock I get:

# ras-mc-ctl --print-labels
LOCATION                            CONFIGURED LABEL     SYSFS CONTENTS      
mc0 channel 0 slot 0 
              DDR4_A1              CPU_SrcID#0_Ha#0_Chan#0_DIMM#0
                                    DDR4_B1              0:0:1 missing       
                                    DDR4_C1              0:0:2 missing       
                                    DDR4_D1              0:0:3 missing
