el-select not showing selected label when v-model is manipulated in beforeMount()
el-select is not displaying the label of the selected option but is correctly updating the v-model with el-option :value. It is probably due to the manipulation in beforeMount() as when that is removed, the label correctly displays the option selected.
However, multiple object copies are required for my use case which is to map headers from uploaded files to expected headers where each file can have the same expected header.
Here's a fiddle with my issue: https://jsfiddle.net/c8auL7fk/

Can you explain what's not working? What should the labels in the el-select be?

I submitted a bug report for this here: https://github.com/ElemeFE/element/issues/13373 and a contributor got back to me.
Vue is unable to catch changes to dynamically created properties. Objects need to be written in an immutable manner.
