Some suggestions for the citation export in Vega:
1. RIS export only - Repeats the first AU field in A1. Solution: Remove A1 field from RIS, or first AU field if always identical to A1
2. RIS export and in-Vega citation - Edition (ET) includes all MARC 250 subfields when only subfield a (Edition statement) is necessary. Solution: Ideally just take first word of 250 $a, less ideally take all of 250 $a only. (Note: Endnote auto-generates the rest based on citation style e.g. takes first word "Eighth" and auto-generates following word: edition, ed., etc.)
3. RIS export and in-Vega citation - Publication year and copyright year are both included in the citation when only one is necessary. Solution: Remove copyright year from citation.
