Powerapps Gallery and Card issue

[Krunal Patel]

I am customising sharepoint form via powerapps and not able to add gallery under custom field card. it always add outside of sharepoint form.

1) I select card Brand-1 and click on Add an item from insert tab

2) Select Gallery and add Blank Gallery 

3) It adds item out of sharepoint form as Gallery* it does not happen with any of other control except Gallery.

@Krunal Patel  and anybody else having this issue:
Although inserting a gallery in PowerApps always seems to add it to the screen's root, it turns out you can then copy and paste it inside a custom card.
But to nest a gallery in another gallery first you have to select the gallery and click on the first row's "pen icon" then you can insert a gallery and it'll be added inside the first gallery as expected.

Thank you for this @Roman_Issa !
