Subscription is synced with a service plan with Hosting settings management disabled and PHP version and handler management enabled.
In case PHP version is changed, the subscription is not locked.
The customized PHP version gets overwritten during the next synchronization with service plan.
This is Plesk bug with ID PPPM-9116 which will be fixed in future Plesk updates.
As a workaround:
2. Go to Service Plans > example plan > Permissions and enable Hosting settings management and Common PHP settings management
3. Press Update & Sync
