How to separate results from extraction with multiple similar fields with regex?

[SMM10]

I am looking through our current alerts and we have a few evaluations that occur like below.

Total_Trade: 129
Total_Value: 300
Total_Amount: 1000

I have a rex like below:

| rex max_match=0 Total_(?<Type>\w+):(?<amount>\w+)

Doing this though I get two fields with multiple events like below.

Type	amount
Trade Value Amount	129 300 1000

What I wanted was each of these to be separate though/

Type	amount
Trade	129
Value	300
Amount	1000

| rex max_match=0 "Total_(?<Typeamount>\w+:\s*\w+)"
| mvexpand Typeamount
| rex field=Typeamount "(?<Type>\w+):\s*(?<amount>\w+)"
