bug in cfg->templates->subcategories per row

[2dmaster]

VM 3.4.2
Configuration-Templates-show subcategories - I SET nothing items per row (set empty this)
get
error 0
Modulo by zero, next i try

in Category -> Virtuemart category view settings -> i set Show Subcategories, e.g. 4, but this absolutely not work, this error too,

work only global param Templates-show subcategories - 1,2,3 per row.

settings in category details - - sucategories -- items per row  absolutely not work T_T

Why not work settings on selected category? I try see 3 subcategories per row but this not work anymore, settings loaded only from main virtuemart config.. Or its my sublayouts template is bad ?? But error 0 I see when set nothing in show categories - items per row
