Unable to modify orders

Since the last update I've been experiencing problems when trying to modify orders. When clicking on the gear icon next to a trade the modification screen opens but often there is no details being displayed on this window or only partial information is displayed and most of these are greyed out so you cannot access or change anything.

Please see the two images below for an example of what I mean. This is on a live account I've been getting this more and more. Each time this happens I have to shut cTrader down and restart it. It will then work for an hour or two before it starts happening again.

I have not seen any problems like this being reported so any idea what might be the cause of this?
