Getting Table Style Errors for Borders?

[ElaineB]

Hi everyone,

We have recently converted RoboHelp to Flare and I keep getting weird CSS errors on any topic with tables. We get an error saying a7a9c (border color) is not valid, but this border color is NOT part of the table styles (any style in the css, really) and there is no visible color in the table that has this code. It is a dark teal color, but there is no dark teal. Help? I have attached screenshots.

It's not a valid color because the code has 5 hexadecimal digits. To be valid, it has to have 3, 6, or another multiple of 3 characters after the #.
It's not showing up because it's not valid. Search for it in the source for the .css file and the page.
