Hi Fillippo,
Great to know that you found a way to fix the first issue. For the second part if you can be more specific I think there are solutions such as replacing the string and re-running the analysis. Check the attached file for an example where I replace fraction radiant.
I know it is somehow a pretty hacky solution but should solve your problem until we find some time to address the issue in a more sophisticated way.
Hope it helps,
Mostapha
