Please let us edit both trigger and limit price

In desktop mode of punch app there are three options market, trigger and limit but my question is why trigger is a different option in punch. trigger should be embedded with market and limit price. Here what is happening when i am switching to trigger then i could only write the trigger price while cannot edit the limit price which is a fixed one shown and when i am switching to limit then there is no option for trigger price and in market also the same . Although in market trigger price is not needed as such .

Please look into this, i am also sharing a scrresnhot of the same.
