It is possible to get combinators to calculate incorrectly: I had initially had the first value as S3 mods, but changed it to 500, it seems it doesn't respect that change and keeps the first setting.
A fresh combinator will calculate correctly, so this is not a high priority issue.

Post the save with the player next to the setup please.

Here you go, new empty game with no mods.
Top combinator is set normally.
2nd is set to each + SP3 output to SP3, works as expected.
3rd is a copy of the 2nd, modified to 500 + SP3 output to SP3, has an error.
4th is a copy of the 3rd, the error stays even with a copy.

Nice find.
Thanks for the save.

You probably don't need this, but I have confirmed the fix.
