Custom Maps not appearing in map list

Okay so I understand this is a frequently asked about topic and I have seen other forum posts regarding it but I am genuinely stumped as to why these maps aren't appearing having read almost anything I can find on the web about it.



I have recently tried installing various custom maps:

This CS office onehttp://www.gamemaps.com/mirrors/mirror/3/13699



This highrise one: http://ift.tt/1xGPeAO



This Zelda one http://ift.tt/1HPuMR5



To name but a few.



Initially I tried installing them just using the steam workshop. The maps did not appear in my available map list when trying to start a solo game or host a game. Because of this I tried downloading the .rom files myself and putting them in the map folder (they are all named correctly with KF- prefix) Still nothing.



This is the case for all of the maps I have tried to install recently but I do have a couple of custom maps I must have installed months ago which work fine (Helm's deep and KF-china maps).



Does anyone know what the problem may be. It's confusing to me that some maps have worked from before but only recently I am no longer able to install new ones.



Here is screenshots showing that the maps are in the folder correctly but still not appearing in the list of maps: http://ift.tt/1HPuMR7
