Movie Maker transitions disappear when video is added

After I browse videos/photos and add them to my Movie Maker project most of my transition options disappear as soon as I choose a file. The basic options are there and there is nothing wrong with them when I use them but it's frustrating that my options are suddenly limited for no apparent reason. It does the same whether I add a photo or video, though I mostly use it to edit videos (mp4) 

I left screen shots in case I'm not explaining well. 

I can't find an answer online easily because when I try to google it most of the complications are transitions not saving properly, I just want to have the options to even use them.

Thanks for helping out!
