It only happens here after the scan has completed.

Now I'm even more confused
Maybe this has been discussed elsewhere, but I must have missed it. Could somebody fill me in, please?

Can you confirm that this is what KProbe is reporting? In other words, that KProbe is reporting the number of rows with at least 1 byte in error and not the total number of bytes in error?

Assuming that KProbe is reporting PI errors as defined in ECMA 267, is it reporting them on a data sector basis, an ECC block basis, or an 8 consecutive ECC blocks basis? It is important to know which, since there are 16 data sectors per ECC block and, obviously, 8 ECC blocks per 8 consecutive ECC blocks. Thus, without knowing which basis KProbe uses, the interpretation of the PI levels could be 8, 16 or even 128 times off their true values.
If KProbe is not plotting on an 8 consecutive ECC block basis, it would be neat to add an option for plotting on an 8 consecutive ECC block basis. That way we could compare the KProbe results directly to the 280 maximum PI errors standard.

This way we could see if the disc is within specifications (DVD and DVD+R) for that particular drive?

what's a "row of an ECC block" ?
each ECC block (= 16 sectors) is subdivided into "rows"? how many? how big is each?
