Highlighting is misaligned with text

[jdandrea]

In Vale VSCode 0.20.0, I am editing an AsciiDoc file, and I see two problems listed by Vale + VSCode:

• Try to keep sentences short (< 40 words) - from Microsoft.SentenceLength
• Consider using 'same' instead of 'identical' - from Microsoft.ComplexWords

Yet when I look at the file editor, the yellow squiggle is underlining a completely different part of the file, and not the word 'identical'. And as for the first problem, it's highlighting the end of a sentence with ten words.

Any idea what I might be doing wrong?
