SX50 file number resets to 001 with new card or formatting even though set to continuous numbering

[Kardons]

I have an SX 50.  File numbering is set to continuous but each time I put in a new card or reformat a card in the camera, the numbers revert to 001.  How  do I get the file numbers to be continuous?
