Charge for failed Loop Outs (30,000 Sats each time)

I've tried to Loop Out twice, but both times it's failed and has charged me 30,000 Sats (each time) for "Cost Server". I thought I shouldn't be charged if the Loop Out failed.

Expected behavior

If the Loop Out fails, I was expecting there to be no charge.

Actual behavior

I was charged 30,000 for each failed Loop Out. My node is also reflecting these charges (identified as "Prepay" in the screenshot attached)

To reproduce

I have reproduced the issue by conducting the Loop Out twice, both times is failed and both times I was charged 30,000 Sats.

System information

LIghtning Terminal

Did you install using Umbrel?
Yes

CMD or Lightning Terminal UI?
Lightning Terminal UI

0.11.2-beta from Umbrel app store

Windows 10
Intel(R) Core(TM) i5-1035G4 CPU @ 1.10GHz 1.50 GHz

Use the reported Loop Out flow in the Lightning Terminal UI on Loop 0.11.2-beta as the starting point, comparing a failed attempt with the recorded 30,000-sat “Prepay”/“Cost Server” charge. Confirm whether failed Loop Outs should retain that charge and establish a reproducible result using the reported system details and screenshots.
