Hi Jim Kyle,
Thank you for your feedback and we have logged internal issue for it. For a temporary work-around, you could try to use a different culture of English(en-gb, en-au) by appending Url parameter ?lang=, for example, use https://survey123.arcgis.com/surveys/<surveyid>/analyze?lang=en-gb to open the Analyze tab.
On the mean time I encourage you to submit this issue as a bug via Esri Support. Our Support team will assign an official bug number for your records. This number can be used to search for and subscribe to the bug on the Esri Support site. If the issue is reported by other customers it will be attached to the same bug report, which helps us assess the impact of the issue and prioritize it accordingly.
