@Rex Lacson, Thanks for posting in Q&A.
For the issue, here are some information you can refer to fix it.
1.Please check if there deployed BitLocker policy to these devices and whether targeted devices have enabled BitLocker on their devices. For the setting, it generically checks for the presence of encryption on the device, more specifically at the OS drive level. Currently, Intune supports only the encryption check with BitLocker. In addition, the setting “Require encryption of data storage on device” does not require a reboot to evaluate Bitlocker compliance. However, the devices are not evaluated as compliant until the drive is fully encrypted. Here is a link with more details: https://learn.microsoft.com/en-us/mem/intune/protect/compliance-policy-create-windows#encryption
If yes, try to sync the device, wait the encryption process done and restart device to see if the issue can be fixed. If no, try to enable BitLocker on these devices.
2.Check targeted devices whether successfully enabled BitLocker.
3.It is suggested that you don't require that setting in Compliance Policy.
Please try above information, if there is any update, feel free to let me know.
