Altium 22 SCH - port's direction disappeared on sheet symbol

[karlik]

Hello,
I messed something up in the 'Project options' during SCH editing and as a result all of the ports on sheet symbol on my top sheet SCH lost their direction - in the properties the ports have their direction (in, out), it is not visible on the schematic.
Furthermore, this apply only to the sheet symbols already placed - if I want to put a new sheet symbol, it is placed with correct directions.

Is there any way to reverse that?
It a rather big design, so I would like to avoid re-drawing the whole top sheet.

Cheers,
K.
