I'm experiencing a mysterious problem with Electrum Bitcoin Wallet on the commanline.
In the beginning when my wallet had no or only a few transactions in the history everything worked fine. The payment-requests are created and stay in the wallet until I remove them. Also state-change (Pending/Paid/Expired etc.) worked as well as the automatic transfer of the payment-requet's parameter memo to the related transaction's param label.
Now the wallet has some more transactions in it's history and payment-requests start to disappear randomly. I'm sure they are not removed by command. Requests which already have a transaction "assigned" seem to be kept, only those created recently are gone.
Here some output from the electrum daemon. Somewhere during this output the payment-requests disappeared. But it also happened while nearly nothing was logged:

After some more research it turns out that it happens during this block from the logs (while syncing a sent payment):
