Humidity staying around mid-60% after adding in humid hide?

Hey guys, I had everything set for a leopard gecko I’ll be looking after, up until the part where I put in a humid hide. It jumped from low 50s to high 40s to low/mid 60s. What can I do to combat this? The gecko is a juvenile, hatching early this year (April). I was looking dehumidifiers for my room, as it tends to be high 40s/low 50s as well (specifically Eva-dry E-333 Renewable dehumidifier) and then adding a lot more ventilation. For those that keep leopard gecko(s), what humidity do you keep it at/try to maintain (I’ve read conflicting information on other posts saying 20-40, 40-50, and then even 50-60 being fine). Thanks!
