Waste percentage not working when creating new batch

The waste percentage at batch portions is faulty, instead of calculating the percentage, it does the following:
If I set it to 10%, it is adding 0.10 to the excess grams.
If I set it to 90%, it is adding 0.90 to the excess grams.

Furthermore, instead of increasing the excess grams, it should decrease that number.

It is irrelevant, whether the groups are filled or not, waste means how much less soap I will have compared to the recipe, and it gives the number which I can divide into portions (groups).

So when I say that for some reason I had to throw away half of my batch, I set it to 50% -> if my recipe would give 1000 g soap, now there is just 500 g soap from which I can create portions, groups, so it substracts 1000*0.5 from the recipe's gram.

But instead of this, when I set it to for example 50, it does exactly this:

1. It takes the grams from the recipe - in the attached example it's 1427.92 grams.
2. Subtract the 1% of it
1427.92 * 0.99 =1413.6408
3. Then it takes the set number (50), and instead of decreasing the value by 50% (1427.92*0.50), it adds 50/100
1413.6408 + 50/100 = 1414.1408

Instead of this:
1427.92 * 50/100
Happens this:
(1427.92 * 0.99) + 50/100


You can see these exact values in the attached pictures.
So regardless of the set value, an initial 1% reduction is happening, then there is an addition instead of multiplication. (By the way, I wasn't able to set 0% neither to waste nor expected shrinkage)

I hope this helps clarify the problem.
