[Fechado] resetting fields that are saved to memory

Background of the issue:
I am working on a site under development and I am trying to update fields that were previously saved. I suspect that some sections on this page (link oculto) were saved with the English content as the Spanish content, and I am unable to edit them.
link oculto

Symptoms:
I am not able to update fields that were previously saved with incorrect translations.

Questions:
Is there a way to clear the translation memory for a specific page or the whole site to allow updates?
