Incorrect thumbail size after upgrade

-- url of the page with the problem -- : intranet...
-- HikaShop version -- : 3.0.1
-- Joomla version -- : 3.5.6
-- PHP version -- : 5.7
-- Browser(s) name and version -- : chrome

Dears,
After site transfer and update I suffer with another problem In Configurattion / Files I have
Thumbnail (width x height) 110 x 110
and
Force images size Yes

but I'm geting 25pix thumbnails on product page independent what I enter in configuration,
in page inspector I can see for thumbnail

img.hikashop_child_image { ...media/com_hikashop/css/style_default.css?t=1489740261
margin: 2px;
height: 25px;
}
img.hikashop_child_image { ... /media/com_hikashop/css/frontend_default.css?t=1489740261
margin: 2px;
height: 30px;
}
All HS files are clean install, and DB transfered from J2.5 and HS 2.3

OK, I solved by RFM... strange place to adjust - 3000 lines file...
