I have SSRS reports with date/time parameters which work fine. Strange thing happens when I click date/time parameter's box while it's empty: dropdown list of unrelated text lines appears below the clicked box. Here's how it looks:
It appears in all reports with date/time parameters. In each report the values that appear are different. In the Development Studio while previewing a report it doesn't happen at all. The parameters are defined as usual in very simple manner. Google search didn't help. :( Can anyone give me a hint, please, what is it and how to get rid of it? SSRS version: 14.0.1016.232, MVS version 2015.
