les label du Apropos invisibles

Bonjour

J'ai ajouté la class Apropos que propose .net par défaut et j'ai obtenu la fenêtre A propos qui va bien, un peu vilaine par défaut.
Pour la mettre à mon gout j'ai gardé tous les labels et boutons qui étaient dessus, que j'ai copié et collé sur la form afin de retirer la "Tablegrid Je ne sais pas quoi" qui imposait le positionnement des différents éléments.

Là dans le concepteur j'ai ma form avec mes labels dessus, tout ont des propriétés a visible, enabled=true mais quand j'ouvre la fenêtre A propos à l’exécution je ne les vois plus !
si je leur donne un fond de couleur, je ne vois pas ce fond à l’exécution, comme si les labels étaient en visible = false ! sauf que dans Apropos.Designer.cs ils sont bien définis comme il faut. Dans le concepteur les propriétés sont OK...

Mais où, quand, par quoi, comment ces labels sont ils modifiés pour que je ne les vois plus à l’exécution ?

voici le code que j'ai dans Apropos.designer.cs
