VERIFIED SOLUTION i
When creating a drillhole cross-section in Discover 10.0 or 11.0, the depth labels and tick annotation from the upper intervals of the drillhole traces are missing, and are instead "overprinted" at the collar position.
This issue was caused by a software bug.
ResolutionUPDATED: September 8, 2017
This issue was resolved in Discover 11.1, available at the Encom website
The issue can also be manually resolved. The drillhole module requires that the HoleID fields are indexed for each of the drillhole data tables (i.e collars, survey, lithology, assays, etc).
Go to Table->Maintenance->Table Structure and turn on Indexing (as below) for each of your data tables to resolve this issue.
