Item value impossible to print in sitemap Android

Hi
I share you my issue to print an item (type String, id is Detecteur_Ouverture_Porte_Garage_Sous_Sol_Heure) into my Sitemap.
The only particularity is this item is updated from rules and has no links with Things.

All other Items have their value but not this one.

my sitemap

sitemap Home label=“HOME” {
Frame label=“Heures” {
Text item=Detecteur_Ouverture_Porte_Garage_Sous_Sol_Heure label=“Heure modification porte Garage”
}
}

My issue on my Android openHAB application sitemap :

you can see, no value is printed…

My item description :

My current value is 08/06/2021 13:31:16 not printed…

Thanks for our help for TIPS to proceed.
Best regards
MacLeod

did you try to add “[%s]” (for a string) in the label?

Text item=Detecteur_Ouverture_Porte_Garage_Sous_Sol_Heure label=“Heure modification porte Garage [%s]”

Thanks for your quick answer.
Your solution is good. As I used the interactive method UI, I thought it was automatically managed… and there was no opportunity to do this.
Thanks a lot for your tips !
