Issue with SLA fields with lower case schema names

On a customer tenant we had the issue on some orgs that with SLA feature enabled on the entity work order the transferred solution created on the target system fields with lower case schema names:

DEV-System with proper schema names:

Exported as managed solution and then imported to a Dynamics 8.2.2.x Online system:

=> now with wrong lower case schema names

Microsoft confirmed in our support case that this is a bug and it was fixed in this version:

Microsoft Dynamics 365 Version 1612 (8.2.2.2518) (DB 8.2.2.2464) online
