The message is because I don't have the latest version?

Hello peleskey,

What is the firmware version you are on?

Can you confirm you on the latest firmware and update if you are not?

Firmware version 6.7.1.20

I would start there. Firmware 6.5.1.3 had a fix listed:

CS4736875, FIELD-2752-Set log level to debugging for "dot1sBpduReceive(): Discarding the BPDU, since it is an invalid BPDU type" messages

This is the current Firmware version 6.7.1.20
