When install plugin with reserved position, for example, 'left' and you don't have this position in your current template then plugin's block will be shown in the first block position in alphabetical order.
For example, if I install plugin with 'left' position and I don't have this position (as well as 'center' position) then block will be show in the 'main menu' position and will break the design.
2 ways of solving this problem:
1) User will get the message while installing the plugin to choose position instead of missing position.
2) Add the block position which will keep all the blocks of missing positions.
