The problem has been reported to engineering. As of this writing, the current version of Threatpulse is 2.0 hotfix 3. The issue manifests itself in that version. For Cloud 3.0 (if and when Cloud 3.0 becomes available), the ability to run a report using "is between" will be removed. The ability to search using the "is between" parameter may be included in a future Cloud release.
To work around the issue, please do not use the "is between" or "is not between" options.
