Warnings in SqlLog when using Cake\ORM\Table::saveMany

Cake 3.3.11 on PHP 7.0.12.

I have a table that has a date column and a text column. I followed the example here: https://book.cakephp.org/3.0/en/orm/saving-data.html#saving-multiple-entities to create multiple entities and save them.

But I’ve found that when the text field contains an apostrophe (e.g. “I can’t do that.”), the Sql Log shows “WARNING: unclosed parentheses or section” even though the row is inserted into the table. Should I be manually escaping these strings?
