System.Object[] issue

[Beercow]

When running Invoke-ATTACK-UpdateExcel, majority of the ID column contains System.Object[] instead of the ID number.

can you give more context?
PS version, OS, Excel version ?

Just tested it on a fresh VM with office 2013 and it works fine, even the new tactics and techniques.
Will post an update later

I'm having the same issue as Beercow; the External IDs sometimes contain multiple values ...
Adjusting the 'ID' property in $Props as follows, fixes the issue for me (dirty solution though):

'ID' = $object | Select-Object -ExpandProperty external_references | Where-Object source_name -eq "mitre-attack" | Select-Object -ExpandProperty external_id

fixed!
