appdesigner: label of listbox still visible when turning invisible

hello,

i tried to make a listbox invisible when using a switch. the switch works so far, the listbox itself is invisible, but the text next to it isnt. i use 2019b. i asked in a mostly german speaking forum about it (gomatlab.de) and the matlab master said it is maybe a bug. when i switch (in)visibility in designmode manually its working tho.

I hope someone can clarify it if its a bug or i am just too new to the appdesigner.

no one anything on this topic ?
