Function boolean return nodes often set to true will default to false once saved project is closed/reopened

The new function output booleans within blueprint class actors are not saving intended true/false entries.

This issue is a regression.

Works in: 4.16.3-3561208
Does not work in: 4.17.1-3586342 and Main

1. Open new project
2. Create a new blueprint class actor > double-click blueprint class actor to open
3. in the My Blueprint panel > add a new function
4. under the details panel > add 4 outputs as boolean
5. on the return node > set true, false, true, false
6. compile and save > close project > reopen project
7. double-click on the blueprint class actor > check that return nodes are set as intended

Results: after reopening the project and blueprint class actor, the return nodes that were set to true, false, true, false is now defaulted to false, false, false, false.

Expected: return nodes to save my previous true/false entries.
