Automation for JIRA fails to add fix version

[Zdeněk Černý]

I want in one edit add fix version to issue and remove other one. I use edit issue and advanced option with this json:

{
"update": {
   "fixVersions": [{
     "remove": {
       "name":"Release Candidate"
     },
     "add": {
       "name":"Version - 1001001"
     }
   }]
}
}

expected result: Release Candidate version is removed and Version - 1001001 is added.

actual result: Release Candidate version is removed 

If I call this via REST API it works also as expected.

if I run 

{
"update": {
  "fixVersions": [{
  "add": {
  "name":"Version - 1001001"
  }
}]
}
}

the new version is added just fine.
