Object not found-description mismatch -Reason?

[Akhila]

Hi,

I have a small doubt regarding the error "description mismatch-object not found"
I found a warning in the QTP result with the following 'Original description'
Visible=-1 [What does this -ve number indicates?]
text=Save
html tab=A
but I confused after finding "html tab=B" for both Run time & test object properties under object spy.
How can I fix it when both of the properties are same? and also what the actual properties I need to check for in object spy?

Thanks in advance,
Akhila
