When switched to EGtag and seleceted first or second edit mode (Root,Strand), activating those modes make objects in object manager "unselectable" (Could be clicked on them and object parameters will be shown in Attribute manager, but they are not highlighted anymore.)

What means they cann´t be deleted for example. Looks like those two modes also create some "invisible" object randomly in viewport space in crazy coordinates sometimes. Solution for that behaviour is disable/turn off those modes (or switch to Brush mode which works without this issue)

To be clear, both modes works well itself, but looks like collides with handling of objects by cinema itself
