Have you checked the R monitor from different simulated files and compare the transmission? the error message says that the result for R is incorrect in size. You can change the Maximum Generation number to be 3 for quick test.

You can also do a simple sweep and see if it gives the same error.

You may also need to update the software. If the problem still exists, you can send us an email for support with citation of the post, and your simulation file, as well as your software version, OS version.
