Analytics Software

When building an analysis and putting a filter on a column, only one value is displaying. This has been working fine until today. we have two filters, year and department.
The only change was in the repository i clicked "Check Out All" and then checked everything back in. i did not make any changes however, was just showing someone how to navigate. I did a check out/in on all in our testing instance and the same thing happened a few minutes later. Now only year 2002 is showing. 2002 is the first year in the backend table that has data. Did i do something wrong?
Thanks in advance for any help.
