Hi,
Based on my test, Data filter does not lost when we re-open the file in Excel 2013. Thus, I think it is not a bug. Thus, please provide us more information to assist you better.
- Did this issue occur with the previous file that created with Office 2010?
- Have you tried to re-create a new file to test?
If this issue occur only with the previous file that created with Office 2010, this issue might be caused by the file compatibility, pleases use compatibility checker to update the files:

If this issue occur with all files even with a new file, please try to repair Office 2013.
Hope it's helpful.
Thanks
George Zhao
