Can you try this a!localVariables(
 local!acctExecs: getdistinctusers(cons!ACCOUNT_OWNERS),
 local!mappedUsers: a!forEach(
 items: local!acctExecs,
 expression: a!map(
 username: fv!item,
 displayName: user(fv!item, "firstName") & " " & user(fv!item, "lastName")
 )
 ),
 local!sortedUsers: todatasubset(
 local!mappedUsers,
 a!pagingInfo(
 startIndex: 1,
 batchSize: -1,
 sort: a!sortInfo(field: "displayName", ascending: true)
 )
 ).data,
 a!recordFilterList(
 name: "Account Executives",
 options: a!forEach(
 items: local!sortedUsers,
 expression: a!recordFilterListOption(
 id: fv!index,
 name: fv!item.displayName,
 filter: a!queryFilter(
 field: recordType!Customer.fields.AccountOwner,
 operator: "=",
 value: fv!item.username
 )
 )
 )
 )
)
