Crosstab conditional formatting in Blue Crystal

Hi community and experts,

I think it is encouraged to use Blue Crystal in Design Studio based on Why use Blue Crystal style in Design Studio apps?

However, I am facing an issue when select on a crosstab with conditional formatting in Blue Crystal theme. (from AO smart copy)

But it works fine in default *Platinum* theme.

When I select a row or column, the alert icon of alternating row will disappear as shown in the below gif .

Appreciate any advice.

Thank you.

Best regards,

Alfred
