Changing description of output in configuration changes its position

[dgarijo]

Describe the bug Example: https://dev.mint.isi.edu/ethiopia/models/configure/CYCLES/cycles_v0.10.2_alpha/cycles-0.10.2-alpha-collection

I changed the description of the SOM file, and it moved the output to be in position 10:

It was in position 2. When I tried to use the UI to change back the position, it does not change (does not save)

I will fix manually the position in the model catalog in the meantime.

I checked, and it does not remove its previous position, it just adds another:
