Yes, I have observed this too. I encounter this daily on both the Nintendo Switch and Microsoft Xbox Series X platforms.
As you also mentioned, the Just For You shop section seems to have an assortment of other issues as well:
- It does not show the correct cost for bundles of which I already have one or more included item unlocked. If such a bundle is selected, then the actual discounted cost (of the bundle’s items that are not already unlocked) is displayed. But, once you navigate back to the main Shop screen, the incorrect “full” bundle cost is shown again.
- It more often than not only includes bundles for heroes that I rarely (or never) play.
- It sometimes includes bundles of which I already have every included item unlocked. So, the bundle displays as “Owned” (which is true I suppose), while wasting a “shop slot”.
- Once selected, some[times] bundles’ screens display the Equip and/or Purchase buttons twice (side by side, near the bottom center of screen).
