The original Aura H2O bezel is in two pieces. The thin top layer is held onto lower layer with double sided tape. It's IR touch, so the lower layer, though black, is a light pipe for IR with curved flanges underneath to pickup IR LEDs and shine on IR phototransistors on the edge of the PCB. That layer is stuck to the screen with double sided tape. The visible illumination LEDs work differently.
If your Clara has a thin top layer then the explanation may be that the double sided sticky tape has bubbled in two places.
