We are using 2.12 and in web control we have the same problem, when we try to sort them by item number it makes it random:
9337300 Resistencia 270K SMD 1206 5%
1426661 Pushbutton Switch SPDT
1377092 Array Resistencias 4.7K 4x1206
1377083 Array Resistencias 220 Ohm. 4x1206
9337342 Resistencia 33K 1206
9336613 Resistencia 510 Ohm. 1206
This is "sorted" by Item link, completely randomized... we haven´t this problem in installed software, only in web control feature...
