I switched the Outline pane to Equations recently and noted that there
was a string of zeros as entries. A little experimenting showed that
these entries corresponded to inline math symbols and expressions I had
added in the current session. On closing the document and opening it
again, the spurious entries vanished.
I've attached a screenshot for a (nearly) minimal example.
For the zeros to appear, it is necessary to enter the maths inset
*first*, Ctrl+M, then type x or y in the inset, exit the inset and then
click on it or another for the zeros to show. Typing x or y, selecting
it and then converting to a maths inset, does not produce the zeros.
Unlabelled display style equations don't produce zeros.
