Narodni Divadlo - English subtitles

Hi,

I'm interested in seeing some local theatre, either at Mahen or Reduta, and the problem I'm having is that the Narodni Divadlo website seems to have a problem communicating clearly which plays have English subtitles and which don't.

The home page will have a small list of ongoing shows with ENG SUB next to a couple, but then I click to the info pages about the plays themselves and it doesn't say anything about English subtitles on there, which leads me to believe there may be other plays showing with English sub options but the website just... doesn't say so.

Does anyone know if there's a clear way to know which have English subs and which don't?
