3 mm markers not recognized with MetroX

During the first scan after purchase, I noticed that MetroX does not see markers with a diameter of 3 mm (only 6 mm), while at the same time my second Miraco Plus scanner perfectly sees both sizes of markers. Is this a software restriction for MetroX or is it a physical restriction? I tried a laser scanner of a different model, it also sees 3mm tags.

Currently RSM software restriction , hopefully temporary.

The reason : the software recognized small holes as small markers , so the diameter was increased to avoid the issue until better solution is available.
