ORD CE 2021 R2 - Item Types Reports are unworkable slow

For a project we need Reports from data out of Item Types / Items. The dgn file is part of a project that exist of multiple 2D / 3D dgn files that find it origin in OpenRoads Desiggner. The Item types are linked to an Excel file wich are linked to Feature Definitions.

This works all as suspected and the possibility to enrich objects with data from Excel, do calculations with it, is seen as added value.

If Reports are created however, thing are going wrong. If a New Report Definition is Created, the computer hangs for 65 seconds (see image below). In MicroStation CE u16 however, this works direct (the reports in the image below where made in MicroStation because ORD was unworkable slow). 

Is it possible to generate Reports with no waiting time like in MicroStation / what am I doing wrong?

p.s. When testing this with a more simple file (see image below), no data is shown when Selected is chosen if a new Report Definition is created..
