In order to copy a value from the multilevel field you will need to go through a couple of steps.
Start by using the following link to get a list of all of the custom fields on an issue and their values.
<your-instance-URL>/rest/api/3/issue/<issuekey>
You can download a Chrome extension called JSON formatter which will make the overview of this much much nicer.
After you’ve done that locate the multilevel field and its' options like so:
For an example, if you were to use the “Melee ADC” option as a summary for an issue you would use the following line of code in the automation rule:
{{issue.fields.customfield_<fieldID>.choice.get(<number of option>).label}}
This will then take the 4th option from the field value and add it as a summary(in this example case).
To copy the current value from the field and add it to summary or another field thies query can be used:
{{issue.fields.customfield_ID.choice.label}}
ID → custom field ID
