If you insert an Space Tile in Meter Screen the console do not check if there is enough space to display all tiles in one row. So i can place 50 Spacers in one row and after that i fill them with the meter tiles. If i press apply the surface wraps them in more rows. In my opinion it is an unwished behavior. Another bug i seen is if you want to move an Spacer the Surface copy it instead of moving.
The software tests this limit only when inserting an channelstrip. When you drag an Spacer from an place in the list to another, the space will be copied. Even if there are more than 24 strips in the list. Then you can fill your spacers with channels – and have more than 24 channels in your view…
