Whilst using the save and continue button in Leads, it can sometimes show an incorrect record which does not correspond to the search filters I have set. Then it will revert to the correct record. So for example I have a custom field called data level which has the options to select Level 1, Level 2 and Level 3. So in my search filter I select Level 1 and click search, I get a list of all the records which are Level 1. This bit is fine. Once I go to edit the record and use the save and continue function, somewhere along the lines, very randomly it will change from showing Level 1 data to all of a sudden showing Level 2 data.

Also we find that where normally a field is mandatory, it can be skipped when using save and continue. I suspect this is a bug.
