Storage size in Roon app on iPad

Why is the size of data and documents in Roon’s app is more than 1 GB?
Is it normal?

Yes 1gb is normal as it stores all the artwork etc.

Can’t understand why is my iPad saves over 7gb of storage in Roon app.

Should I need to clear the cache in the Roon setup?
If I do that will it damage the data for roon?
