Frequency 2, click with linear mode

Hello,
Problem in the Nuendo 11.30 final.
I have about 500 tracks that go into several stems (10) 5.1.
I have inserted a frequency 2 EQ on each Stem and I have activated the linear phase on all bands.
From time to time depending on the automation changes there are digital clicks because of the frequency in linear mode.
Has anyone had this problem?
Here is my plug in chain
Thank you
