New to Remnote. Question about cpu usage and indexeddb folder size

I started using Remnote (on linux) only last week and have < 10 documents created. I would guess my total data is a few kB. I noticed that the indexeddb.leveldb folder is constantly increasing and new files get created even when Remnote is idle. The folder is about 1.7G and seems to be increasing about 500M per day. The folder currently has ~900 ldb files.

Possibly related, the app also seems to use 30-50% of one core even when idle.

I’m guessing this is not normal?
