Strange phase shift of 360° from 180° to 540° in a waveform plot

Dear EasyEDA team,
can you please explain what causes the strange phase shift of 360° from 180° to 540° at around 20 µF in shown waveform plot?

@UserSupport,

The EasyEDA plot shows completely the wrong phase. When the netlist is run in LTspice it looks like this:

I have asked that the plotting of AC Analysis results in WaveForm be fixed but it still seems to be broken.

:)

@mathias_magdowski,

Sorry but your link does not work.

One of these links is the one you needed to post:

Thanks @andyfierman for the quick answer and thanks for correcting the link.
I had also simulated the same circuit in LTspice and can confirm the results you obtained.
I had also already posted them on Twitter and will therefore only share the link and not again copy the figures here:
