Validation failed on existing files

[txau]

Ie. The main file for this entity https://cejil.staging.uwazi.io/en/entity/ghe3c5yxrfw gives this type of error, in entity edit but also when labeling data on the ML interface.

For me there is a concern with why do we have entity structure that is inconsistent with the templates? I think we are doing a lazy-delegation of data update on entities the next time they are saved, but this causes issues when presenting data that need to account for properties that may no longer exist on the template definition, etc. and we have overhead code to deal with this scenarios that probably shouldn't happen. So maybe the true solution is just to ensure entity data is correct at all times?

We need more info into if this is an isolated entity or if this is a common problem that could occur in other scenarios.
