Dynamic filter loses value of custom field

-- HikaShop version -- : 2.6.0
-- Joomla version -- : 3.4.8

Hi!
I have a problem with dinamic filter by custom field. I have 15 values of the custom field.
In dynamic mode filter displays only 11 values, but I have products with all values of this custom field.
Previously I changed the filter values - may be it is the reason. But I don't know how to fix it....
Can You help me, what could be the problem?

Hello,
As it's said on the documentation

That option enables you to change the options of the filters according to the previously selected filters. For example, if all your products are computers with 4Go Ram and 250Go hard disks, if you select 4Go in the first filter, the second will show only the 250Go option and not the other values.

Hi Mohamed !
I found the reason of the problem) I import products with some incorrect values. It was a space on the end of a words. "Buket" and "Buket " - it was stupid of me Thank You so much for Your recommendations)))
