confusing burn-in setting in "Discrete: rates "

[plemey]

For the user it may not be immediately clear that the burn-in needs to be set as a fraction, so please label it as 'select burn-in fraction'. Also, there is no scale shown for this fraction (under the tick marks) and the highlighted value is confusing. For example, at times, it shows the value of '0.1' at the first tick mark, which would make sense:

However, after fiddling with it, the value at the first tick mark became '0.0014'?:

checking the completed analysis indicates it was actually 0.004 something?
