Hi Aaron and Ashley, I have looked into this and so far I am unable to reproduce the issue on my own org. The issue can be reproduced in yours with a simple LDM that contains as little as one date dataset connected to another dataset with one fact, therefore we can rule out any issues with the LDM connections, at least something.
In order to continue looking and testing further, could you please share how the date is being declared in your Snowflake? Are you using any unusual data type? Also, was this always an issue or if it started recently, could you provide a time frame?
