The alignment must also be set to the Left margin. That's the first setting to check.
Format > Text > Align > Left
If the alignment is correct, you must also specify that the writing direction is left to right or LTR to get the writing to start on the left margin for some text layout software.
Format > Text > Paragraph - Writing Direction > Left to Right
