Hi Everyone,
I have a PowerApps Canvas app that I've made and I've created a custom Multi-Select checkbox to achieve a functionality I wanted in the app. I've been facing a weird problem with the form I've made. When I've created a new form and selected a few check boxes as seen in the image, once Ive saved my answerers to my SharePoint list, and I go to make another new form the selected checkboxes from the previous form remain on the screen. I've tried to fix this by Clearing the collection in the Onselect property of the new form button I have but It doesn't seem to fix my Issue.
Could this issue stem from the checkboxes themselves? As you can see in the image that all my collections have been cleared but the checkboxes remain checked. How can I fix this please 
For my checkboxes here are all the formulas I have active in properties for my checkbox's:
Default: If(*Authorisation_to_work_permit*.Mode <> FormMode.New,Self.Text in Concat(*Permits_DataTable*.Selected.'What Hazards could I face?',Value,","))
Oncheck: Collect(colHazards,ThisItem)
OnUncheck:Remove(colHazards,ThisItem)
Text:ThisItem.Value
