IBM Fidelity NetBenefits 401(k) balance off (between Windows and Mac versions)

As of today, my Mac's One Step Update/download has caused my IBM Fidelity NetBenefits 401(k) balance to be off (compared to Windows)
I'll have to wait until next banking day to see if it resolves.
Tuesday as it turns out (no banking, Labor Day ;-}
Are other IBM NetBenefits users seeing a balance discrepancy issue between Windows and Mac versions?

Any help appreciated!
