Hello everyone,

I am trying to run a time-variant Clearance model as shown below. My problem is that when I use the Inspect function and see the CSV file I only get one estimation for CL for every patient and it is not changing over time as expected.

Here is the CSV file:

Everyone has been so helpful with my issues thank you in advance,  
Thanos

@achamzas have a time varying clearance component in one of my models and The results look reasonable as following:

I just run the same code today and it works. It was probably a bug that was fixed with the new version. Thank you!
