Test case labels for OMASA in `scripts/config/self_test_ltv.prm` contain `1Dir` or `2Dir` even though the LTV metadata files contain both 1- and 2-directional metadata interleaved. Proposed fix: remove the invalid string parts from the case names. <!--- Below are labels that will be added but are not shown in description. This is a template to help fill them. Add further information to the first row and remove and add labels as necessary. -->
