I get the following error message when trying to load a MATLAB R2020a Model Advisor Configuration JSON file in MATLAB R2020b:

Unable to load check "mathworks.jmaab.jc_0627". The check information specified in configuration file might be different than information needed for this release of the check. For example, if the number of check input parameters has changed from a previous release when you open the configuration file, the check does not load.
I confirmed that the check "jc_0627" exists in both R2020a and R2020b.

To produce this issue, I selected only "Check usage of Discrete-Time Integrator block (jc_0627)" in Model Advisor and saved it as a JSON file through the Model Advisor Configuration Editor in MATLAB R2020a. Then I loaded the saved JSON in R2020b through Model Advisor Configuration Editor. However, when I tested the above same workflow in R2020b to R2021a, there is no compatibility issue. Why is there a discrepancy? I get the following error message when trying to load a MATLAB R2020a Model Advisor Configuration JSON file in MATLAB R2020b:
