Paid button toggle sometimes doesn't work in order list

[role74]

Hi there

After upgrading to VM 3.8.6 build 10373 i've noticed a bug that wasn't there before.
In the Order list there's this button to indicate if the invoice has been paid or not. In the past I was able to toggle unpaid orders independent from it's status. This doesn't work anymore for some orders in the current version.
When switching the status to confirmed it also usually sets the "paid" status correct, but not on one specific order. If I set the status to "shipped" directly (without payment) I can't toggle it at a later state to indicate the payment has been done. It stays in "unpaid" state for this order. I've not seen this on any other orders yet, just on one. I have to mention that the specific order has an amount of less than 1 EUR (0.85 CHF), that's the only unusual thing.

Green message in the header appears "Order state updated successfully" (Bestellung Bundesstaat erfolgreich aktualisiert - Translation bug )

Using Joomla 3.9.22 and PHP 7.4.12

Thanks for your advice
