Setting up SLAs per priority will not work properly when different languages are involved

Issue Summary

Setting up SLAs per priority will not work properly when different languages are involved

Steps to Reproduce

1. Change your Atlassian Account to a language other than English at https://id.atlassian.com/manage-profile/account-preferences
   • This was replicated using Brazilian Portuguese
2. Setup SLAs on a project with priorities shown in that language
3. Add a default SLA

Expected Results

SLA follows the priorities selected

Actual Results

SLAs will all fall under the default SLA, not matching the defined priorities

Workaround

Set the SLA using English as your language.

Note: when accessing the SLA using a different language than the one used to set it up, it'll also show an error besides each priority.
