When loading attributes for linear asset (at the same time adding classification), attributes are duplicated. One set is with values, other is without values. Those, with values, are added soemhow as additional attributes.
If I remove checkbox at ISLINEAR, then everything loads as expected.
If I’m adding just classifications, then there is just original set of attributes (of course, without values).
Yes, it is so. It is something related to default object structure. Our support company created new object structure, now it works as intended. It doesn’t help much, but yes, there is issue, and yes, there is solution. I’m not still so technical adanced, I can’t tell where exactly is issue.
