Kindle Oasis 8th gen Jailbroken - No Option for Book display Lockscreen

So I recently reset my Oasis and jailbroke it on 5.14.3 and all is well, but For some reason the option to have my currently reading book set as the lockscreen isn't appearing. I know I can manually set the lockscreen with it being jailbroken but was wondering anyway I could get this feature to reappear since I had it before.
