Injector Values

Had an issue with a no-start this morning that I eventually got running.
2003 x5 3.0l, went to start this morning, just turned over and randomly sputtered (sounded like no/little fuel).
Finally got it running and seemed normal.
Hooked up bimmer tools through my phone and scanned, no codes relevant.
Checked the injector section and found these values:

First set of numbers is at idle (warm) and second set is after bringing it up to 2000rpm and those numbers reflect while its returning to idle.

So, i'm not very familiar with injector values but to my knowledge this means that injectors 4 and 5 are bad: either clogged or faulty?
Any input on this would be greatly appreciated!

Edit: just noticed that it may not be clear but all the injector values are in fact "+" not "-". The app shows all the numbers as positive values but what I copied and pasted it seems it would show as minus.
To my understanding, positive value adjustments mean less fuel and more air?
