Trouble removing release dates from TV episodes

Two episodes of an existing TV season will not air on the dates IMDb has listed for them.

Deletion attempt #1:

#260819-210243-969000

#260819-210337-296000

My comments were "episode not scheduled", and I included a link to the online schedule from the broadcast channel showing that they aren't listed anywhere for those dates.

IMDb declined the delete with Reason Does not meet contribution guidelines.

Second attempt with more evidence:

#260821-150605-099000

#260821-150716-077000

Not only did I once again include links to the online schedule showing no listing for that show on those days, but I included another link showing that the episodes will not air anytime in the next two weeks.  Additionally, I included a third link with evidence that the show is on hiatus, and that no further episodes are scheduled to air.

IMDb declined the delete with Reason Does not meet contribution guidelines.

I have reviewed the submission guide and do not find anything that wouldn't allow a release date to be deleted if it is incorrect, and no new release date is known.
