What version of Grid2 are you using?

 vr916 -classic

What game client version (windows or mac) and language are you using ?

 Windows Classic

What steps will reproduce the problem?

Be in a raid, set a character to Main tank role, watch as main tanks do not appear at the top together

  
Did you try having Grid2 as the only enabled addon and everything else disabled?

Doesn't apply

Was it working in a previous version? If yes, which was the last good one?

 Probably not

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

Please provide any additional information below.

Basically the Layout for Role is trying to set the Retail dungeon role layout which has no equivalent in Classic,  I found a way to change that layout to use the Main tank, Main assist roles in the raid roles that are set by the raid leader instead
Basically in the GridLayoutLayout.lua do edit the following:
FROM

Grid2Layout:AddLayout("By Role", {
	meta = META_ALL,
	[1] = {
		maxColumns = 8,
		groupFilter = "auto",
		groupBy = "ASSIGNEDROLE",
		groupingOrder = "TANK,HEALER,DAMAGER,NONE",
		sortMethod = "NAME",
	},
})<br /><br />

 TO

Grid2Layout:AddLayout("By Role", {
	meta = META_ALL,
	[1] = {
		maxColumns = 8,
		groupFilter = "auto",
		groupBy = "ROLE",
		groupingOrder = "MAINTANK,MAINASSIST,NONE",
		sortMethod = "NAME",
	},
})
