It's not uncommon for trace files to have data for a particular statement mixed in with data for other statements. Toad tries to watch for the StatementID's to pull them all together, but sometimes those statement ID's get reused for different statements, so I have to be careful to not just always combine data when the statement id matches.
So it may be that the data is in there somewhere, just in an unexpected position in the file.
Or maybe it really is missing - who knows. These files are not well documented.
try searching the file for "BINDS #11529215045667076728" and maybe you'll find more Bind#10, 11, 12 elsewhere in the file.
If so, send me the file and I'll see if I can piece it together.
