2018 no horn chirp after activating Intelibeam

[comtech5]

I have a 2018 Tahoe and have discovered that upon activation of Intellibeam feature, the next time I turn off and exit vehicle the horn will not chirp upon pressing the keyfob lock button twice. No doors are ajar and deactivating Intellibeam does not cure the problem. I must go into settings and although the horn box is still checked, I must turn the horn off and then on again to correct the problem. Does anyone know of this? Is there a TSB on it?
