I wonder would it be feasible to get this fixed professionally. Maybe open a seam , repair the baffle and re glue the seam. Would it be worth it on an old yam sib
When I inflate the right chamber the front chamber inflates also and vice versa.
When I deflate either I can hear the sound of air rushing and both deflate
I have had this on a few ribs in the past , its not uncommon, if tubes are holding air ok other than leaking between chambers I personally would leave it alone. That's just my opinion.
