date ranges are lost when creating smart groups
If you conduct a search using a core date field and specify a date range (not a relative date range, but a regular date range), then save the results as a group.
When you open the group, the results will be as if the date was not specified at all. When you edit the smart group criteria the date range is not there.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
