These are the month options when selecting a date. Please push a fix asap! 
Dear @Kevin3, I’m so very sorry about this issue you had to encounter!
I’d love to say that we’ve applied a fix, so everything should work fine now.
If it’s still an issue for you, could you please send me a link to the page with the widget in question? We’ll be very happy to look into the issue and find out what’s going wrong.
Again, I’m so sorry for the inconvenience caused 
I’m afraid I’m still not seeing a fix. When I try to create a new form and choose “date” as the field type, the dropdown still shows the wrong months. I’ve also done this in incognito mode and still have the same issue.
Thank you for the update, Kevin!
That is strange, cuz I still could not replicate the issue on my end… Do you have an option to check the widget in another browser and let me know if the issue still persists?
If it does, could you please name the browser you use and send me a screencast of what you see? It might help me understand the issue better, and I’ll try my best to provide a solution for you.
