Funny HTML after Import
 

Hey,

I recently used Impex to transfer my phpBB forum to VBulletin and it seemed to go great.

I've noticed that in my users signatures, the BB code has changed.

So the users who had center and bold tags around their signatures etc, now have this code:

Code:
[center:opfgdqvv][/center:opfgdqvv]
[center:dv2zutsv][/center:dv2zutsv]
[center:33wcuwt9][/center:33wcuwt9]
[center:2q8pacei][/center:2q8pacei]
[center:2q8pacei][/center:2q8pacei]
[center:opfgdqvv][/center:opfgdqvv]
[b:1xwliiyx][/b:1xwliiyx]
Is this normal, and does anyone know how I can fix this?

Thanks, appreciate it
