HTML Editor BUG

I have a table with a field called “detail” (BLOB field type)
I have a Form that for the “detail” field I have HTML Editor
When Adding a new record no matter what I do, the result of the saved record DOES NOT format the data entered
Example:
I entered into a new record the following with a Font=12pnts [SIZE=10px][SIZE=12px]This is a test
line 2
line 3[/SIZE]

[SIZE=14px]The result when saved:[/SIZE]
[/SIZE]
[SIZE=10px]This is a test[/SIZE]
[SIZE=10px]
[/SIZE]
[SIZE=10px]line 2[/SIZE]
[SIZE=10px]
[/SIZE]
[SIZE=10px]line 3[/SIZE]
[SIZE=10px]
[/SIZE]

I ran a test using SC7 and compared to SC8
As you an see from screenshots, SC7 works perfectly, and SC8 does NOT
Please can someone tell me what to do to correct this.
This is in production and needs to be corrected urgently
