Block properties text bug

When you paste to a block's properties (those you can edit those with the wrench icon tool) the text keeps re-aligning and I've even seen the spacing between the letters change (this happened on a cannon's "Power" property where I copied its own properties and then pasted them and the text would go from "P O W E R" to "POWER").
I know it's a minor thing but you never know where a small bug can lead to.
If you need any further info you can just reply here and I will answer.
