Describe the bug

I have a ActionButton, i use the MRTK3 ActionButton prefab.
When i click it in the editor sometimes i have 2 error:

This one is from CanvasProxyInteractor of MRTK XR Rig MRK3 3 prefab:
UnityEngine.XR.Interaction.Toolkit.XRBaseInteractable:OnSelectExiting (UnityEngine.XR.Interaction.Toolkit.SelectExitEventArgs)
Microsoft.MixedReality.Toolkit.MRTKBaseInteractable:OnSelectExiting (UnityEngine.XR.Interaction.Toolkit.SelectExitEventArgs) (at Library/PackageCache/com.microsoft.mrtk.core@66c690c1a686/Interactables/MRTKBaseInteractable.cs:291)
UnityEngine.XR.Interaction.Toolkit.XRBaseInteractor:EndManualInteraction ()
Microsoft.MixedReality.Toolkit.UX.CanvasProxyInteractor:StartSelect (UnityEngine.XR.Interaction.Toolkit.IXRSelectInteractable,UnityEngine.Vector3) (at Library/PackageCache/com.microsoft.mrtk.uxcore@13263b650b38/Interop/CanvasProxyInteractor.cs:74)

UnityEngine.XR.Interaction.Toolkit.UI.UIInputModule:Update () (at Library/PackageCache/[email protected]/Runtime/UI/UIInputModule.cs:132)

This one is from The component UIGUI input adapter of ActionButton :
An Interactor received a Select Exit event for an Interactable that it was not selecting.
UnityEngine.XR.Interaction.Toolkit.XRBaseInteractor:EndManualInteraction ()
Microsoft.MixedReality.Toolkit.UX.CanvasProxyInteractor:StartSelect (UnityEngine.XR.Interaction.Toolkit.IXRSelectInteractable,UnityEngine.Vector3) (at Library/PackageCache/com.microsoft.mrtk.uxcore@13263b650b38/Interop/CanvasProxyInteractor.cs:74)

UnityEngine.XR.Interaction.Toolkit.UI.UIInputModule:Update () (at Library/PackageCache/[email protected]/Runtime/UI/UIInputModule.cs:132)
