When you first visit transaction page in CKB explorer, it shows the deprecated address by default.

(https://pudge.explorer.nervos.org/transaction/0x2c4183cd1cdbd3e3a5d06a22d42800c65f7ee2a68d500e9bd46a36bc665b8e9c)
Only if you turn off the switch then you can see new long address instead short address in each visit.
I think you may set this switch on by default. It may bring confusion for the users who visit explorer for the first time as the shown address is not the same as the new long address we recommend.
