Hi Dasha. Thank you for taking the time to highlight this on King Care. Our technical team is aware of this issue and will investigate it to try and find a solution as soon as possible.
In the meantime, there seems to be a workaround. Please go back and play these levels: 7, 10, 17, 19, 33, 48 and 164. You do not need to complete them, just play them. This should unlock the boosters.
