If I search SCN with these words: delivery split shipping points vl01n
then I get 82 hits. I just opened a few on the first page and got several with a correct answer.
If you had read them then your evidence given with the screenshot should actually look much different.
The message is just SAP standard, if would be sufficient to tell the exact message with the message number, a screenshot for the same is not needed.
Instead you could have posted a screenshot to show that your shipping points are not different, that is main message in the message, isn't it? None of your screenshots shows a shipping point.
