Hi all,
This is my first time posting on this forum so please notify me of any faux pas i make
,
I received an IFC file from which I have to make a quantity takeoff. I thought revit would be a suitable program for that since it has the wondrrfull material takeoff function. But when i create a table i noticed that for some reason all elements have a different string of 6 numbers behind the family name.

The yellow part is the name of the family the underlined part is the type that has been added to the family name for a reason i don't understand and at the end is the string of numbers. 
If i select said column the properties tab shows it isn't part of a family.
So my question is twofold is this a known issue with importing IFC moddels and are there any fixes for this problem
secondly is there a way to let the takeoff schedule group together these slightly different named objects.
Thanks in advance for any new insights and my apologies if i asked a question that already has been answered.
P.s. sorry for the two extra attachements i could not see how to remove them after uploading
