Reference file incorrectly offset in y direction

We sometimes experience problems with attached reference files that are not properly located. The problem arises both with attached models from the same design file, but also when attaching models from other design files. In the clip below you can see an example where the same model is attached twice but is shifted approx. 2.6m in reference slot 1 (the designfile is attached). The only difference i can see is that the orientation is inaccessible for the reference in slot 1 while the rotation is 0° for the reference in slot 3.

We use Bentley Map SS4 but the problem is the same in Opencities Map Update 5, which is where the screenshot comes from.

I hope someone can help us.
