Though it's a minor bug, it's a noticeable one. In Russian localisation plated blocks, for example Copper Plated Block, have the name Блок покрытый медью, but there is a comma missing. In order not to put a comma in it, but still fix the bug, you can call it Покрытый медью блок. Sorry if this seems like a pain in the arse

Stairs and slabs have the same problem
Proposed changes:
Ступеньки покрытые медью -> Покрытые медью ступеньки
Плита покрытая медью -> Покрытая медью плита
This also applies to other metals, but in those, as here, the first word just needs to be moved to the end
