Once you are your done styling the keyboard how you want it are you downloading it and then setting it check out my screenshots (probably won't post in order)
Yes. I have done those steps. I style it, i download it and name it. I then select it from my themes and its also selected in theme park. Uploading some screen shots for you or anyone else to see
There is also a light and dark setting could be you are styling it to the light theme but you are using dark theme so basically there are 2 different styles to choose 
@ButtaBean_420, I noticed that too. My light mode and dark mode settings are both styled. I am using dark mode setting on my phone. Uploading more screen shots. I also did the effects and key animations and all of those are working even though my styled keyboard isnt loading
@ButtaBean_420 another thing to note is that i cannot get any styled keyboards to load, even the preset ones that come with the app. All that shows up is my customized keyboard that i made as shown in this screen shot
See the difference on and off
