Error on second action when trying to update a change a field used in the trigger

I am learning automations and I have hit an error I cannot figure out.

There are two tables involved in this automation:

1. People table where the client master data resides
2. Client Funding table where clients' stipends and grants get recorded

Here is the logic I am trying to make happen:

1. When Client Funding Indicator field changes to "MicroGrant Invited", do two things
1. Create a new Client Funding record for the client <-- This step works correctly
2. Reset the Client Funding Indicator field to "Funding Not Specified" <-- This step gives me the error "Received invalid inputs."

Thank you!!!
