When running optimization scenarios the following error appears telling me that i cannot use "Import to meet shortfall" in optimization scenarios.

Knowing that when I turn it to Requirements remain unmet, the results vary a lot (from when setting optimize to "No" and leaving it ImportToMeetShortfall)

The error:

The following are the different results that appear comparing :

1st the optimizing with "requirements remain unmet"

2nd the results with no optimizing and "ImportToMeetShortFall"

3rd the results of an old run with the correct results I want now.

Also the same thing happens in another variable "outputs by feedstock fuel " When running optimizing the years from 2042 to 2050 don't appear. The following are pictures comparing :

Can you please help me out?

Thanks in advance.
