Is the property with the "number" type Bitrix not shown?

Question

1C-Bitrix

For some reason, the filter does not work correctly on the site santelux.ru/catalog/santehnika/ .
There are several properties:
Width
Length
Height

But for some reason only "Width" works correctly. prnt.sc/13835w4

All three properties have the "Number" type, but again only the "width" is displayed in the filter
prnt.sc/1383cbn
prnt.sc/13837rl

All the necessary checkboxes for displaying in the filter are checked.

And if we change the property type to "string", for example, then "length" appears in the filter as a list or checkboxes, which is not at all convenient
