Product variation attributes are misordered after product import from Excel file

Hi,

I have following problem with product attributes:
I have hundreds of variable products and each product has its own variations (attributes) – different for each product. Some of the attributes are containing numbers+sign (like for ex.: “Ø63 (100)”), other are containing letters+number+special character(for ex.: “16×2.0 на кангал 75м. с изолация 6 мм ( 0.040 W/mK) синьо фолио”). I used an import tool to import all variable products from an Excel file. In my file the variations are ordered correctly. However after import the attributes in the back end and in the front end of the site are misordered. I can not set Custom ordering for attributes because I simply have tons of different attributes. How can I fix this?
