Minecraft & terraria have disappeared from me and all my family members purchased

So I purchased Minecraft on my dads iPad in 2012 and terraria on the same iPad in 2014. I’ve used them semi frequently since then but, recently they have both disappeared from the shared purchased on all the up to date devices we own. I have screenshots from my dad of the purchases in the purchased history but they do not appear anywhere else. I last time I accessed them was probably a year ago and I’m unsure of when they disappeared.
