Recurring budget amounts do not repeat correctly

Hi, I’m trying to make a budget in excel whereby all the income & expense items and amounts are regular and recurring.
In my example, the dark blue is the original data which I want to repeat by highlighting and dragging down and the light blue are the resulting entries. As you can see, the text replicates perfectly but the amounts do not, plus the blank space in the amounts column now seems to include an unwanted amount. How can I fix this please?
