Why are the assembled blocks not included in the remote relay?

[Lanskih90]

Hi,
The builder assemble the blocks and sends them to the remote relay, while I do not see errors when sending, I see messages (submitted capella block and submitted block).
But when I go to the relay link to check if the block was included in the relay, it is not there.
Links to check blocks:

Can someone explain to me why this can happen, or what I don't understand?

I have read somewhere that these might not be included simply bacause the bid isn't high enough to compete with the others that had been submitted.

Bud, would you actually mind if you posted the logs or the geth with verbosity debug, leading up to the submission of the block? Possibly also the flags you are setting. My builder just isn't sending them to the relay at all. Thanks so much in advance if you do decide to help.
here's a ref to my issue:
