Incorrect true/false import from a CSV file

Greetings to the whole community. The question is simple: I imported a CSV file into Adalo, a file that also contains a true/false field. However, when importing, the field in question, despite the original Google Sheet column having TRUE and FALSE, everything is imported to me as TRUE.
Am I doing something wrong? Does any special preliminary operation need to be done? Thanks in advance for anyone who would like to answer me
