### Root cause

Prior to merge of #11924, SimApp calls [module/NewManager](https://github.com/cosmos/cosmos-sdk/blob/2b549b807c13f66dca68965206163ca400d0dbe0/simapp/app.go#L344), which implicitly sets sane default values of [OrderExportGenesis](https://github.com/cosmos/cosmos-sdk/blob/2b549b807c13f66dca68965206163ca400d0dbe0/types/module/module.go#L239) from the modules passed as parameters.  Since this usage was deprecated in favor of [RegisterModules](https://github.com/cosmos/cosmos-sdk/blob/823d2a7f28f10a360b543748a6e90e01bb5d3c23/simapp/app.go#L354) in the app wiring work, `OrderExportGenesis` was now `nil`, resulting in empty `genesisData` in [ExportGenesis](https://github.com/cosmos/cosmos-sdk/blob/823d2a7f28f10a360b543748a6e90e01bb5d3c23/types/module/module.go#L339)



### Fix

Explicitly set `OrderExportGenesis` with same module order as `OrderInitGenesis` from `SimApp`.
