Validate mission start title not showing number of labels to validate

[misaugstad]

Brief description of problem/feature

As pointed out by Frank (a partner in our Taiwan deployment), the count for the number of labels is not showing up in the mission start tutorial on the Validate page. In the pic below, the title should say "Validate 10 Surface Problem Labels".

Potential solution(s)

The translations in validate.json (with the key mst-instruction-2) seem to be correct. If I manually enter the following into the console, I get the correct answer.

i18next.t('validate:mission-start-tutorial.mst-instruction-2',{'nLabels': 10, 'labelType': i18next.t('common:surface-problem')});

So maybe we aren't passing in the label count correctly anymore!
