Artefacts in Sentinel-3 SLSTR L2 LST cloud mask

Hi,
I am noticing some strange patterns in the bayes_in cloud mask, for example in this Sentinel-3 L2 LST product:
S3A_SL_2_LST____20220914T102040_20220914T102340_20220915T192058_0180_090_008_2160_PS1_O_NT_004.SEN3

Is this a known issue? Is there any way to detect products where this issue occurs (e.g. from metadata) to discard them before downstream processing?
Thanks!
