Yes, you are absolutely right. I actually had that in my mind to review, as I'm not sure the limits of the parish match the ones of the monument (and strongly suspect they do not), so I'll have to look into the legislation. With all probability 2 items will be needed there, as you say. Sorry for the revert, I thought it was because of some misunderstanding with the origin of that database (it was produced from scrapping back in 2011, from the DGPC and SIPA sites, not by direct input, which would probably generate the issue of self-referencing). I removed the parish from P131 for now, until I fix it. Thanks for noticing that!
