Undefined variable: oldRefId

Hello,
on Today Screen an error appears (unfortunately I don't know from when - probably after last update) - it is attached

In log is:

I have did a temporaty solution when I added this to the code (before failed if):

if(!isset($oldRefId))
$oldRefId = '';

if(!isset($oldRefType))
$oldRefType = '';

Which works. But it would be better if you correct it on your side

Thank you...
