Description

If one layer is joined to another and no prefix is selected (by selecting custom field name prefix and then just blanking the box), the resulting join layer column are all one to the right of the one they should be.

For example layer 1 with field 'ID', joined to layer 2 with 'ID', 'Height' and Width', using the selected prefix '2' would have the height values in the height column, but when it's joined with no prefix (custom prefix, blank box), the values that are under 'Height' in layer 2 appear under 'Width' in layer 1.

I just ran into this problem today, using QGIS 3.4.
I believe it may have something to do with identical field names existing in each table.
In my case, the OBJECTID field heading gets removed from my joined table, by the values in the column remain, and the next field to the right becomes the field heading of the (former) OBJECTID column.
