Sale of Stock only reported in year end summary

I sold 50 shares of Fisker Inc on 07/15/24 for 0.00 proceeds.  I purchased the shares on 02/12/21 for $875.  My 1099 B from Schwab does not report it on the 1099 B that is provided to the IRS but shows it on the Year-End Summary that is not provided to the IRS.  

 

It is listed under Long-Term Realized Gain or (Loss) --"The transactions in this section are not reported on Form 1099-B or to the IRS.  Report on Form 8949, Part II, with Box F checked."

 

Why is it being treated different than my other sales?  Obviously, I want to claim the $875 loss but would have liked it to be listed on my 1099-B?  Is the IRS fine with listing sales that aren't on a 1099-B??  Can you explain why they listed it in this manner??   Thanks!!
