 The new Evoker mechanic of Echo spell duplicates any abillity that you are casting to any unit under Echo buff, it also works for hots and it creates an additional hot buff with different spell ID. If you use Echo buff on any unit and then cast Reversion buff on him it puts two buffs at the same time and due to it grid2 not showing any of them. But if you use Echo buff on some unit and use Reversion on someone elese it shows two buffs on two units correctly. Seems like it's bugging when they are on the same target. Also one more note that Reversion spell has an specific mechanic that if it crits it's counting up the duration on a few second, so when these two buffs of Reversions are on the same target and they are not showing, if any of them crits and extends their duration, grid2 updates I guess this buff and start show them even when there are two. So when I use echo and reversions spells together on the same target I have to wait when it crits or put one more buff to refresh this Hot to see this buff on my frames. This problem also exist with other ability like Dream Breath which also puts two buff with Echo and not showing when they are together. Unfortunatly it doesn't have any exend mechanics so you can't see them when they are together on one unit. 
I think it can be soled if there was a feature which allows you to create 2 buffs statuses with the same name but if I'm trying to add one more buff of Reversion with different ID it won't let me cuz I already have this buff with such name. Maybe Groups of Buff is the way to just write all kinds of buff of this spell and maybe it will show correctly but it looks like a "crutch"
Sorry for my english I hope you understood me

By default grid2 tracks spells by name, you have to create a second buff and enable the "track by spellid" option on both buffs.

You can create two buffs for the same name, you have two options.

Use a prefix to create the buff (valid prefixes separators: @#>), examples:

SecondReversion@367364

ReversionEchoed#367364

Evoker>367364

This is explained in the tooltip displayed when you put the mouse over the spellname editbox.

Another option is to write a different name for the status, type for example:

SecondReversion

and push create.

After this go to the new created buff configuration window.

The first option is a edit box displaying "SecondReversion", replace this name with the desired SpellID number and check the "track by SpellID" option.
