Victor,
This is normally a result of making some manual edits to the apps config.json file. Here is a snippet of a standard config.json:
....
{
"position": {
"left": 55,
"top": 45,
"relativeTo": "map"
},
"placeholderIndex": 1,
"id": "_5",
"name": "FLHover",
"version": "2.12",
"closeable": true,
"uri": "widgets/FLHover/Widget",
"config": "configs/FLHover/config__5.json",
"openAtStart": true
},
{
"position": {
"left": 105,
"top": 45,
"relativeTo": "map"
},
"placeholderIndex": 1,
"id": "_6",
"name": "myWidget",
"version": "2.16",
"closeable": true,
"uri": "widgets/myWidget/Widget",
"IsController": false
},
....
Notice placeholderIndex 1 has a position of left 55 and top 45.
