Hello,
I have a "Company Name" drop down menu users are able to manually input to create new options. When I start typing part of the company name then see it drop down (as the option already exists from being added on before) and select the option; after I save and exit it shows the value I had typed in instead of the one selected from the drop down.
Eg.
1. I wish to record "AMCR" as the company name. I type "AM" and see "AMCR" has already been added in before and select it from the drop down.

2. After clicking from the drop down it displays "AMCR" as the selected option

3. After hitting save, it displays in the list as "AM", the original value I had typed in. Despite it appearing to have been selected from the drop down option in the form.

How can I have it display correctly as the option that was selected in the form but still retain the ability for values to be able to be manually added it?
Hope I've explained this well- thanks in advance!
