[Bug]: disputes multiple candidates on Westend

[ordian]

Bug Summary

Kagome's validator seems to be disputing multiple candidates

Bug Description

As you can see here: https://westend.subscan.io/event?page=1&time_dimension=date&module=parasdisputes&event_id=disputeinitiated

From time to time, there's a burst of disputes initiated that seem to be coming from the Kagome's validator (5CAsa5uG1i3Duq5NM1g8zYjNvUCwkwADxgFQiypSLTg6Hnwm).

You can see also the validator is getting much lower rewards:

compared to others:
https://westend.subscan.io/validator/5C556QTtg1bJ43GDSgeowa3Ark6aeSHGTac1b2rKSXtgmSmW

A likely reason for less rewards is that you don't sign backing and/or availability bitfield statements.

In addition, we are still observing #1853 coming from your validator.

Steps to Reproduce

Run a testnet with at least one parachain producing blocks and supermajority of validators based on polkadot-sdk and at least one Kagome validator. At some point, you'll observe your validator raising a dispute for some reason.

Effects of the Bug

See the description.

Expected Behavior

The validator should not raise a dispute for valid parachain blocks (candidates).

System Information

Not relevant.

Additional Context

No response

I think it was fixed as we didn't see any disputes in westend for 26 days as of today
