E-file rejected due to ForeignTaxCreditSource/USTaxWithheldOnDividendAmt

My 2020 e-file was rejected due to

/Return/ReturnData/IRS1116/ForeignTaxCreditSource/USTaxWithheldOnDividendAmt

 

I have two 1116s with two passive income from RIC mutual finds each. There is data in taxes withheld in US dollars for both columns and the grand total for all for is correct on first 1116.

 

I've stepped through the interview for Foreign Tax Credit and don't see any issues. There are no form errors and it passes final review. Where should I be looking for the missing data?

 

I do see the thread "E-file rejected due to ForeignTaxesPaidOrAccruedDt on Form 1116" that suggests a bug, but my reason for rejection was actually different.
