Hi @NL-KB
Looking at your regular expression, a few things
- the colon does not need to be escaped with the backslash "\:" should be ":" instead
- in your example, you do have an empty value for "Content" which is not working with your regex
You may want to make the capture groups optional by adding a question mark "?" after each group.
Meaning, it will still require the colons to be present, but will also allow empty values
^(.+)?:(.+)?:(.+)?:(.+)?:(.+)?$
You can test it here

Also, keep in mind that you will see undefined in your values if visitors did not come with UTM query params to your site.
Hope that helps
