Thank you for bringing this to our attention. It appears there’s an issue in how we are keeping dates on filters inside the screen. I am logging this as a known issue in our tracking system so I will archive this ticket here. There is not a target date for getting this issue addressed yet but our devs are aware of it. 

Hello Skuid Community ~

This has been addressed in the new Millau 11.1.14 release which is now available on the Skuid Releases page.

As a reminder, Salesforce does NOT allow reverting back to prior versions of managed packages. Skuid always recommends installing new versions in a non-business critical sandbox environment to test all mission critical functionality before installing into a production environment. We also recommend that you update out of date themes when you upgrade.
