Hi isabelarias,
Hidden widgets technically still exist on the page, so any widgets (hidden or not) in the push/pull path of a widget will still be pushed or pulled. I’d recommend checking out Anthony’s post here to see what would be considered to be in a widget’s push/pull path:
https://forum.axure.com/t/push-pull-and-groups/34240
As a workaround in this particular case, what you could do is place both of the groups in your file in separate dynamic panels (by right-clicking them and selecting “Convert to Dynamic Panel” from the context menu). Since content within a dynamic panel can’t push or pull content outside of the panel, this would prevent your tabs from pushing/pulling each other unexpectedly.
I’ve gone head and attached an edited version of your file below. Please let me know if you have any questions or if I misunderstood anything!
