Any idea why this happens?

>> object.encrypted_attribute?(:shirt_size)
=> false
>> object.shirt_size
=> "{\"p\":\"RXVPZmvtjjmcQx0l9Uz1Lxc=\",\"h\":{\"iv\":\"YSM3ZNA5cmHUBP97\",\"at\":\"ISLUxeXBehUW84cJq90wog==\",\"k\":{\"p\":\"B/WuyQk/BN46s4csjSpTwZ9fyOd60s3rS3ByfmZ84U4=\",\"h\":{\"iv\":\"bPGIcsJYY/b38veK\",\"at\":\"nB/mhZu0LRkxCL7IBJCYYQ==\",\"e\":\"QVNDSUktOEJJVA==\"}}}}"
>> object
=> #<PersonalInformation:0x00000001406fab58 id: 33, person_id: 34749, shirt_size: "[FILTERED]">
