Time value does not match expected format with exposed date popup

I'm sorry you've ran into this problem.

There's an existing issue where some people are looking into it too ( 🐛 Time Field Inserting a Blank Space Needs work ), I'm closing this issue so please follow the other one. Thank you.

In my testing the 2 if blocks referenced in that issue are not hit during execution so I don't think the two issues are related
