Setting doesn’t work

I have just upgraded Poll Maker to pro version but since the upgrade several items of settings are not working:
1- In styling whatever colour I choose as Main shows up on text, icon everywhere.
2- Adding CSS code freezes the plugin.
3- In settings, unchecking Title doesn’t work as Title still shows.

I also need to know how to fix the height to fixed pixels as I need the poll to fit in a specific size of 350×230.

Any help would be appreciated.
