Basic JavaScript - Record Collection

Tell us what’s happening:
The other test are passed but I’m failing these two. I don’t know why.
After updateRecords(recordCollection, 2548, "artist", "") , artist should not be set
and
After updateRecords(recordCollection, 2548, "tracks", "") , tracks should not be set

  **Your code so far**
// Setup
const recordCollection = {
2548: {
  albumTitle: 'Slippery When Wet',
  artist: 'Bon Jovi',
  tracks: ['Let It Rock', 'You Give Love a Bad Name']
},
2468: {
  albumTitle: '1999',
  artist: 'Prince',
  tracks: ['1999', 'Little Red Corvette']
},
1245: {
  artist: 'Robert Palmer',
  tracks: []
},
5439: {
  albumTitle: 'ABBA Gold'
}
};

// Only change code below this line
function updateRecords(records, id, prop, value) {
if (prop != "tracks" && value != " "){
  records[id][prop] = value;
}else if (prop === "tracks" && records[id].hasOwnProperty("tracks")==false){
records[id][prop] =[value];
}else if (prop === "tracks" && value != " "){
  records[id][prop].push(value);
}else if (value === " "){
  records[id][prop] != "tracks";
   delete records[id][prop];
}
return records;
}

updateRecords(recordCollection, 5439, 'artist', 'ABBA');
