Question about adding a capacitor to the signal line going into the IN12 pin of the LT4321

I am using PoE (10Gbase-T+802.bt T4-CLS8 (PD 71.3W)) through the LT4293+LT4321 solution.

During verification, there was a phenomenon in which packet loss occurred when PoE of 10Gbase-T link performance was applied, and it was confirmed that symptoms improved by prescribing a capacitor to the PoE Center-Tap for PoE on the RJ-45 side.
The related circuit diagram is as follows, and C1730: C1733 is a prescribed capacitor.

Please advise if the added capacitor above can affect the PoE BT operation.

Waiting for your answer.

Thank you.
