Digital Wellbeing doesn't have timer options: detects mine device as fully-managed

I am using Nusantara ROM (Android 12) and my device is RMX2193. The device isn't managed by an enterprise so I can't understand this Digital Wellbeing shows

timers aren't available for work apps or fully managed devices

Please note that app timer is no longer a Pixel exclusive feature since the last few years. See the bottom-most part of the screenshot " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy">
