We’ve delivered some data validation using dependent properties and EDS in a custom developed ICN plug-in as described in this tutorial https://www.ibm.com/support/pages/validate-customer-data-when-saving-document-or-folder. But when we enter this field, all records are marked as incorrect and have a message of successive letters from the message "customValidationError". It only works when you make any change to the layout of the entry template (setting a label, reordering properties or adding a container, etc.) and saved, the validators stop behaving as expected. Before changing when we use the Entry Template document with the standard ICN property list container (without the Entry Template) or using the Entry Template but only with the default layout, it does't mark the required records as error.

This looks like an existing support case. Please look to the support case for feedback / next steps.
