You cannot (and should never) give the same Field Name to a field in the same table twice. This causes Users no-end of confusion when building reports.
That is not to say that on a Form Layout, you cannot change the Label Text of a field to match another, when a User is viewing an Approval from Device 1 versus an Approval from Device 2. However, your Related Reference fields should indicate the source-table, even if they have similar names (Device Name - Table X and Device Name - Table Y) for example.
By default if you add a field with a name already in the table, Quick Base will append the next sequence number to it (2, 3 etc) because no field should be duplicated. There are some situations where a duplication has been "allowed" but as an Admin or a User you should never want the same field name to represent two different data sources.
