Tangy Checkboxes are not scored correctly

[lachko]

Create a subtest like this one: https://glitch.com/edit/#!/rhetorical-cord-rate with two or more checkbox group questions. The score here is the sum of each of the options for the checkboxes. The total is the sum of all options for all checkboxes on this page (this part already is shown correct on the client dashabord)

Now try selecting different response options and see how instead of summing the values, tangerine only gives 1 points per selected option. We want to sum up the actual value of the selected option (not just one)

For the below student I get mediocre when I have select almost all options
