Retirement tax questions

THere is a contradiction here:

 

The Broker DID ENTER a cost basis amount on my 1099-B yet also says that the "basis wasn’t reported to the IRS" on the 1099-B. So if the IRS is getting the same form as me as stated by @DianeW777 , then the IRS DOES receive cost basis info in my case.

 

So based on what was  explained by @JamesG1 "that in some cases the brokerage does not know your cost basis and therefore does not enter an amount", there is a contradiction! Why are they reporting an amount yet also saying it's NOT REPORTED to the IRS?
