It's hard to tell what might be going on based purely on a screenshot. I'm guessing that the theme isn't being applied inside the dialog.

Same problem here with mat-card-title and mat-card-content

Using mat.theme and color-scheme as documentation mentioned, when dark mode is active title and content has very low contrast color to the background.
