Lock Screen Not Working.

I just bought this app, and customized a simple lock screen. So i lock my phone. (I set My Original Lockscreen to none) But when i turn on my phone. It shows nothing but my background. No clock, no swipe indicator, no nothing. But if you swipe, it unlocks like normal. Im not sure why this is happening. But please help. Im on a Samsung Galaxy S8 Running android 9 [PIE]
