从powerlogic原理图COMPARE PCB图之后出现以下字样，请指点，谢谢

从powerlogic原理图COMPARE pcb图之后出现以下字样，用原理图更新PCB后也出现这些字，会影响pads LAYOUT（画PCB），怎样避免这种提示？具体如下：
TTRIBUTE DIFFERENCES
---------------------
Attribute Level [ Schematic Parent -> PCB Parent ]
Attribute Name Schematic Value PCB Value
PARTU3 -> U3
Geometry.Height 78.74mil
PARTD12 -> D12
Geometry.Height 59.06mil
PARTQ2 -> Q2
Geometry.Height 57.09mil
PARTQ3 -> Q3
Geometry.Height 57.09mil
PARTQ4 -> Q4
Geometry.Height 57.09mil
PARTQ5 -> Q5
Geometry.Height 57.09mil
RULES DIFFERENCES (Values in mm)

*DEL_ATTRIBUTE* PART D12
"Geometry.Height"
*DEL_ATTRIBUTE* PART Q2
"Geometry.Height"
*DEL_ATTRIBUTE* PART Q3
"Geometry.Height"
*DEL_ATTRIBUTE* PART Q4
"Geometry.Height"
*DEL_ATTRIBUTE* PART Q5
"Geometry.Height"

在logic添加这几个元件的Geometry.Height 属性
