Hello. Without doing anything, after a while, when I went to the Lightning Swap section, I was surprised to see that it was possible to increase the receiving capacity.
It was probably just your connection to Electrum's official swap server or a temporary issue in the server. (
as seen in the screenshot)

It should be noted that you need to send some small transactions to activate the receive transaction.
Sending a small amount has nothing to do with being able to reverse-swap (
Send LN -> Receive on-chain) since all it needs is enough sending capacity on your channels.
And your on-chain wallet isn't limited by you channel(
s) on how much it can receive from the reverse-swap.
