[KBFS][Win10] The KBFS Sync and Block Caches do Leak!

At first i thought this Issue came from my System, but after a reinstall, i found out that this must be related to an Bug. I am using my System since 3 Months now, and im often using KBFS to edit Rich Text Files, so i found myself pretty wondered as i saw around 100gb been taken by KBFS. Heres a list: AppData\Local\Keybase\kbfs_sync_cache\v1\diskCacheBlocks.leveldb - contains lots of nearly identical sized .ldb Files with an total of 90gb AppData\Local\Keybase\kbfs_block_cache\v1\diskCacheBlocks.leveldb - same here, lots of .ldb Files with an total of 12GB

I havent had BSODs or something similar Happening, Keybase runs on start and stays active till i do shut down. Running Win 10 64 2004, Keybase is installed on an M.2 SSD which is also the Systems Drive.
