Actually it is an old issue and i have already highlighted this to their senior management when back in 2022 i had sent feedback via mail to them........ Whenever there is an LCN change then although old channel is allotted New LCN and a new channel arrives on previously held LCN slot but logo displayed still remains to be of the previously available channel on that LCN
since mid 2023 they have taken some corrective measures to address this issue but still can be seen happening at various times, hope same is properly rectified soon
