Same TimeTrigger Function on two Function App sharing same storage account

Function App name: TimeTrigger
Tools used: Visual studio
New V4 app or existing V3 app migrated to V4: Existing V3 app.

Hello,
after the migration from V3 to V4 we discovered the HostId issue (Function App name was 33 chars) has host id was truncated so azure function was going down. According to what I read I have define two different custom truncated HostId with AzureFunctionsWebHost:hostid.
This has generated a bug where TimeTriggered function was run twice from both the App. Should I change the HostId to be same for both function app or is it a bug.

Thanks
