Realms 30 day trial not properly working.

I recently wanted to see if realms. and the bonus content would be worth buying. I started the 30 day free trial. And since I've started the trial it tells me I can't download any of the free content like texture packs or the map packs which were added with the realms trial. I started the trial a few days ago and at first I could download content, but now it constantly tells me my PS4 has no space to download any content, and I have over 400 GB of space available. Please help mme solve this issue, and thank you for your time.
