Issues in De-embedding

I applied de-embedding function in PNA to different traces to see its effects.
For low loss and well matched structres, the de-embedding worked pretty well. However, the de-embedding had issues with high loss (>10dB) or poor match strutures.
Can you explain why this is happening?
Is this due to measurement unceratinties or de-embedding function?
