I have made a global dimension with a lot dimension values.
When a chose dimension ex. 'V1958' (and some other random values) on the salesline and afterwards view dimensionvalues with Ctrl+Shift+D,
NAV has changed it to 'V1008'.
It does this with most of the values I enter on the salesline, but some of values it keeps and when NAV changes the value it's always with the same value 'V1008'.
