@Hatedfate that is really strange 
The reason I originally suggested upgrading your PennyLane version is that there was a known bug in v0.20 of PennyLane that was causing the Adapt-VQE demo to give the incorrect results — the same incorrect results you posted above.
A bugfix in v0.21 fixed this, and reverted the Adapt-VQE demo to give the correct results.
Could it be that your Jupyter notebook kernel is using a virtual environment that has PL v0.20 installed, whereas PyCharm is using an environment with PL v0.21?
