Error using "systemIdentification" when an app created by App Designer is open

When an app that has been created in App Designer is open, an error occurs when trying to import data in the System Identification UI.

The error I get is:

Error using matlab.ui.Figure/set

Functionality not supported with figures created with the uifigure function. For more information, see Graphics Support in App

Designer.

Error in iduipoin (line 17)

set(win_point,'pointer',point)

Error in sumboard>localDataImportCallback (line 695)

iduipoin(1);

Error while evaluating UIControl Callback.

Is there a work around for this? The GUI that is created with app designer is to make signals for use with the systemIdentification toolbox and it is very inconvenient to have to close it and reopen it every time I create new signals.

Thanks
