vfs.fs.size [# FSNAME, pfree] is not supported

[mfdzerohour]

Good morning, if I use the zabbix discovery feature, it shows me the information related to vfs.fs.size [# FSNAME, free], showing the information correctly, now if I use vfs.fs.size [#FSNAME, pfree] it shows as unsupported, if I inform you what would be the partition vfs.fs.size [/, pfree] it shows me the result, ie it is something related to discovery, someone went through it? Or should I report it as a bug? I am asking this question because as I am still starting with zabbix, there may be errors on my part, and not the same, if it is zabbix error, I would like to inform the same, if you can answer me thank you.

Do you use set "Type of information" to "Numeric (float)" in the item prototype of pfree?
Please attach a screenshot of pfree item prototype configuration ("Configuration -> Hosts -> Discovery -> Item prototypes -> item with pfree").
