Reports 2.0 Bug

The Reports 2.0 filter is auto formatting my case # and removing the 2 zero's at the beginning of my case #. As a result I cannot use the "=" sign, and can only use "contains" to make sure it captures the remaining numbers.

Is this a bug? I tried adding a " ' " to the beginning like you can in Excel, but the filter still keeps removing my zero's.

Ex: '00479005 turns into 479005

Any reason why or how to fix?
