RLS show single value in card visual

Good morning everybody,

i got RLS implemented in this report, where every user is greeted by a slogan defined by the current time and by his first name. 

I also got a table visual where (when the user opens the report) it shows his very own open holiday and gloding time hours. 

(My perspective)

 (User end perspective)

Now (like i tried in the user end perspective photo) i only want show the open holiday for the logged in user in the card visual.

Can someone help? 😄

Thanks!
