Unit placed in wrong subcategory

[Wild_Weasel_31]

Not my own mod, just tried to sort them by subcategories.

I changed \Saved Games\DCS\Mods\tech\<mod name>\Database\Navy\*ship_name.lua file by adding line

GT.tags={"Cruiser"};

But it persistently appears in "Submarines" subcategory, whatever sub.cat. name I set.
Editing similar .lua file from the same mod worked perfectly.

Is there any other part of the code responsible for setting a unit subcategory in Mission Editor?
