Currently Installed 8.0.13-rc1 (b2020051415)

Nested UDT’s within a primary UDT are failing to pass the parameters in if a modifier is used to the downstream tags. The below image is what parameters get passed in. I add the “.Interlock” to be added to the Nested UDT. This parameter is being passed into the Nested UDT but not to the Nested UDT tags.

Thanks for any support on the matter.

Was on phone with IA for this same issue today. It was a regression from 8.0.12. The fix is supposed to be ready for 8.0.13 release.
