No you are not at fault.

Hint: While you could legally log sole manipulator PIC it might be best not to do so for those two flight! Don't try to erase it if you already logged it though.

Downside is that you will need to check the yes box about incidents (or accidents if enough damage occurred to meet the FAA definition). This will not hurt you at the interview since you were not complex endorsed and had almost no complex time. But it may possibly move your app further down the stack so you might not get called as quickly by the majors. But plenty of other folks have to check various boxes as well.
