Hi,
The Rows and Columns configurations of the board view apparently are linked to the label/name of the relation instead of the name of the Type. If the intended design is indeed to keep label/name of the relation, then changing the label of the relation should not break board view immediately like it is doing now. This change should be transparently reflected in the board configuration without breaking the board view (making it unloadable).
Thanks!
