Imported > Export Issue: Messages is not in chronological order and all of them appears blank once going inside each of conversation

Recently, I migrated all my backup of SMS messages to a new device, and ran into few issues while exporting the sms, and importing. The following things happened as listed below,

1.)when I open most of the conversation, it appears to be blank; no data can be found, while the weird part is that the preview message are visible for each SMS.

I exported SMS few times again and found the size was incorrect, notice its "0 bytes".
2.) In addition, all the message appears to be in random format( Date ) instead of chronological order. It has combined the archived page and top level page.

3.) I also tested with other messaging app, all the messages are not displaying correctly. It seems to be the issue with fetching json file correctly from the start.
