iOS: cursor position sometimes does not correspond exactly to where text is inserted

I do not know what causes the cursor to be a few spaces ahead of, even on the next line from where characters appear as you type.

Sometimes rebooting the iPad clears it, sometimes not. Typing seems to happen anyway, but it throws one off to have the cursor position not correspond exactly to where text is inserted.

I wish i could provide more details about this. If I notice something additional, I’ll add it here. The complement of software on the iPad has not changed for months.

Thank you!
