An error when opening RCM 30m compact data

When I use SNAP open the RCM 30m compact SAR data, the system reminds me that there is already a band name ‘i_RCH2’, but it is OK when I use it to open the 5m data.
One possibility is that the 30m image is cropped into many small parts, but SNAP does not recognize it.
I hope the bug can be resolve as soon as possible.
