Prop Hunt server - Can't select all maps on the voting screen

[pontehh]

Okay,
So i got the map voting to work by changing developer of the game mode prop hunt. This one is made to work with ULX. Check it out here: [url]http://steamcommunity.com/sharedfiles/filedetails/?id=182739498[/url]

The voting screen pops up after 10 rounds, showing all the available maps. From here everything looks good.

But then when I want to select a map it doesn't work. And If i start spam-click on one map that doesn't work from the first time, let's say cs_office, it puts the vote on a another map, far away from the one I know I clicked on. It seems like only 4-5 maps is electable, the rest are bugged. What am I supposed to do?

Comment if you want me to attach files or pictures of anything specific.
