Sampling Time issue for linearization of continuous time model

I am trying to follow these steps ( Linearization Tool Simulink ) for linearizing my model, but I am getting the following error:
Root Inport [...] has a sample time of [0, 0] which does not match the sample time [0, 1] of its destination [...].
I only have continuous blocks, so I'm confused. Displaying the sampling times, I see that constant blocks have the sampling time set to "inf" (as I think it should be), but the sampling time is marked as Fixed in Minor Step, which is different from Cont, see the figure.
What I am missing? Thanks!

I found a workaround: The problem arises when this FiM value is fed back into an "in" port of another block, where (for a continuous signal) the sampling time should be [0, 0] but is wrongly inherited as [0, 1] from this FiM thing.
If you manually set the sampling time of this in port to [0, 0], simulink does not seem to be complaining anymore.
I would still be interested if anyone knows more about this FiM business (or if this is a bug), as I find it very strange.
