SPELLCHECKER NOT catching MISSPELLED WORDS

[Waverly]

What is wrong with the attached spreadsheet the spellchecker is not picking up on the two misspelled words and cells C2 & 11?

It is not picking up the misspelled words of TENNANTS or AMMOUNT

I've open the same spreadsheet file on two or three different computers and none of those computers is touching the spelling errors.

Check you setting in:
File -> Options -> Proofing -> AutoCorrect options.
I think issue is that both words as written capitalize.

Untick "Ignore words in UPPERCASE"
