Revert changes to version 17.1.1 - they were committed inadvertently. Remove 17.2.1 - this document should be created by the tester from the clean test document. Related to Issue [DSB-897]
Reverted changes to test document for 17.1.1 - I should have used the test document proper ("Test Document DSoilModel.xlsx").
Adapted the test document proper (some typos, added C-Phi/Su-berekend where necessary). Created an empty test document for version 17.2.1 (copy of the test document proper).
