Backglass missing
What it means
No backglass will show for this table on your backglass screen.
Why it happens
B2S looks for a .directb2s file matching this table's exact name right next to it — if it's not there, or named even slightly differently, nothing displays.
How Pincab Toolbox detects it
No .directb2s file with this table's exact base name exists in the Tables folder.
