Cyrillic Language Kit: Keyboard Stickers Don‘t Match the Keyboard

I am using the Cyrillic Language Kit, and I am trying to use the keyboard stickers that come with it. I am following the included keyboard diagram, but there seem to be too many keys on the second row of letters (a, s, d, etc). The label sheet and keyboard diagrams show 12 keys on this row, but my keyboard has 11. The last key on the row is "E" (E with umlaut) in the Russian layout and ")" in the Bulgarian and Ukrainian layouts. Where do I put this sticker?
If you are using a US keyboard and a Russian, Bulgarian, or Ukrainian keyboard layout, this last sticker goes on the "\\" key, just above the Return key.

If you are using the Cyrillic-QWERTY transliterated keyboard layout, there is no key that corresponds with this character. The "E" (E with umlaut) is produced by the Option-e key combination, and parentheses are produced just as with a standard US keyboard layout. For details, see page A-19 of your Cyrillic Language Kit Installation and User's Guide.
