Can anyone explain me this

First this message: We accepted your bid to boost a proposal. This is a refund for your total bid.

Then this: 

We accepted your bid to boost a proposal. This is the final bid charge.

Refer to img I attached please help me to understand this. 

Thanks to mods.

Hi Rehan,

Thank you for reaching out to us. If you boost, but are knocked out of the auction before receiving an eligible interaction, you will not be charged. You can find more information in this help article. 

Additionally, I’ve escalated your community post to a support ticket. One of our agents will be in touch with you soon to assist.

• You'll be refunded your bid if you're outbid from the top 4 slots before the client interacts with your proposal.
