Why is the Interface golden and wont open in the update 4.24?????

I updated to 4.24 and before when i used the 4.23, i could click class settings/add interface/compile and then when it pops up in the interface tap, i would double click my selected interface and it opens up. Now when i go inside the updated 4.24 version of the ue4 engine, i noticed my same interfaces i saw in 4.23 are now gold, then when i try to click on them, they will not open!? Why wont they open? is there something extra im suppose to do? how to i open my interfaces like in 4.23??
