Widget_Label is showing deleted readings

[bam91]

I am using the label widget to show my appointments and the locations on my smart mirror with an tabletui page. When there is an appointment with an location and the next appointment has no location, the appointment without location shows the location of the last appointment when the first appointment is deleted.

Example: appointment 1 (location 1) appointment 2 appointment 3 (location 2)

Now appointment 1 is gone and deleted . So the Reading t_001_location gets deleted from the calendar-device. But my tabletui is showing this:

appointment 2 (location 1) appointment 3 (location 2)

When i am opening the page new, everything looks fine and is showen correctly. So it has to be a problem with caching or something like that.
