As you can see, the “Comunicacion” column marked in red shows strangely the ncRecordHash values, while the “Denuncia” column shows the correct description.
NocoDB displays Primary value of the linked table in LTAR column. One of the reason for this I could think of is that the primary column in Airtable base was configured say as a Formula & is not migrated to NocoDB (and NocoDB picked next available column to display as Primary value, in this case it was ncRecordHash).
You can go to the related table & update Primary value field to something else of your preference.
