Simulink data type mismatch when using atomic subsystems

Dear,
I am updating a model to be multirate instead of running entirely on one Task timer. Therefore, I was thinking on using atomic subsystems.
When changing the two root subsystems (“TestRig” and “FastTask”) to an atomic subsystems with each there own sample time, I receive an error related to a datatype mismatch:
Data type mismatch. Output port 1 of 'Mastermodel/Rate Transition1' is a signal of data type 'uint8'. However, it is driving a signal of data type double. This message is related to a hidden RateTransition block.
While when compiling the original model with non-atomic subsystems, I have no issues with data type mismatches.
For your information, all input and output port signals are virtual busses with signals of different data types.
I also attached a screenshot of the model root and the subsytem's block parameters.
Any proposals on how to resolve this issue?
Kind regards,
Niels

Can you use a data conversion block before or after the rate transition and cast to either a double or a uint8?
