TilemanLayer's [Paint] - [Tile Effect] - [Object Group] is unavailable

When setting up the TilemanLayer tileset, selecting [Paint] - [Tile Effect] - [Object Group] and pressing “Add Element” does nothing.

While it is possible to set this up via [Select] - [Tile Effect] - [Object Group], this is a workaround, and since I usually use it from the Paint function, I would like this to be fixed.

The version I am using is Action Game Maker v1.0.10.

It certainly doesn’t display, perhaps due to the process of loading the group…? For now, I’ll submit a report.
