#22952
(Old) MTA does not work if 2 (or more) milestones with the same name exist
This is the deprecated variant that is still used in Prime:
The error occurs because the MS designation is used as a key for the series and no series with the same name may exist in a dataset.
Now the milestone itself is used as key for the series, so everything seems to work.
Test
No test.
