Posts missing from Kyon Ko Datte Yuuutsu pool (which I can't add to)

The pool Kyon Ko Datte Yuuutsu (pool #401) is incomplete. Two additional posts should be included in it:
post #349047, which should go after the current 9th image in the pool, and
post #349050, which should go after the current 11th image.

I tried to add them to the pool, but even though the pool is listed as "Public", it doesn't appear in the drop-down list that appears when you click on "Add to pool".

Any help and/or fixes would be appreciated.

I remain,
Sincere.

Someone unchecked the "Active" box, possibly because of forum #32300. I added them.

Thank you very much!

I think I did that because it looked, and by all means should have been, complete. Can sub-priv not edit pool status either?

By the pool history, it was me who removed it from Active status, thus it disappeared from the "Add to Pool" dropdown (which only includes Active pools). As Log mentioned, it seemed to be complete, and completed doujinshi should not be marked Active.

Re-adding Active status is simple enough. I confess that I don't know if sub-Priveleged users can add or remove Active status.
