[BUG] Two mutations at the same position in BA.2 Spike:+N440Y and BA.2 Spike:+N440D entires in isolate_mutations.csv

[by256]

Describe the error

In two Omicron-mutant entries in isolate_mutations.csv, there are two mutations that appear in the same position.

To locate the error

In https://github.com/hivdb/covid-drdb-payload/blob/master/tables/isolate_mutations.csv

BA.2 Spike:+N440Y has two mutations at position 440:
Line 21808 - BA.2 Spike:+N440Y,S,440,Y,NULL,NULL
Line 21816 - BA.2 Spike:+N440Y,S,440,K,NULL,NULL

BA.2 Spike:+N440D has two mutations at position 440:
Line 21840 - BA.2 Spike:+N440D,S,440,D,NULL,NULL
Line 21848 - BA.2 Spike:+N440D,S,440,K,NULL,NULL

See the screenshots below.

Expected behavior

I believe the 440K mutations should be removed from these entries, as this is the usual mutation in BA.2 at position 440.
