Hello Sir,
Thanks for choosing our product and I am very sorry to hear that you are facing this problem. This kind of issue does not normally occur. Currently, you might not be seeing the pro features because, after installing the pro version, the plugin customization settings move to the theme customizer. You can find the BNav settings by going to Appearance >> Customizer. Alternatively, you can watch our pro customization video for guidance.

If you still believe you are facing an issue, please send us your site credentials through a private reply. Our development team will be able to investigate the problem.
Additionally, please note that due to our festival holiday, our response time might be slightly delayed. We appreciate your patience.
Thank you.
Bishal
