Error : Input number red transmissivity must be between 0 and 1

Just came out to this issue on the “glass modifier” component. While the transmittance input parameter si set to 0.99 in the slider, the component seems to receive 1.07774160512.

Solution exception:Input number red transmissivity must be between 0 and 1. Got 1.07774160512

Am I missing something ?
