Yes, I've already been through this; it's a familiar issue. In general, yes.
1) As others have suggested, this is purely a "bug" in the "EWA_CoolTip" mod, which affects the display of troop numbers because the author changed the size of the unit icons. Without this mod, "sworn enemy" is displayed correctly in the game itself. Although, I understand that you've already figured this out yourself. )
2) This is not the only flaw in the "EWA_CoolTip" mod. You may also want to slightly shift the display of the numbers to the right, as the "500-999" numbers have the "5" heavily cropped.If needed, the file for editing the position of the troop numbers is located at "EWA_CoolTip.h5u\UI\Tooltips\CommonAdvObjTooltip". The file is "CreaturesNumber.(WindowTextViewShared)". I set the "x" value to 38.5, which I think is the optimal shift. If you make it smaller, the "5" is cropped; if you make it larger, the number goes too far to the right and appears outside the creature icon.
