Refeuling is very, very slow

[Captain45]

Using P3Dv4.4 GSX level 2. QualityWings 787-900

In te past it worked fine using the slider at 5 times the speed.

But since an update the refueling is deadslow. My car at the usual filling station goes faster. If the green message on the top left corner is accumulative (I think it is) than it does just a few galloms a minute. I tried with and without Prosgressive checked. It makes no difference. I checked the manual but couldn't find a way to speed it up (other than cancelling Couatl).

P.S.
I did a little test loading 11,400 kgs of fuel and after 26 minutes the green text is at 3431 kgs. Acceleration 5 times Progressively unchecked. And... with accelleration at 10 times, it is just as slow. No difference.

For other reasons I had to uninstall/re-install GSX. So I checked the refuel speed again. With Settings at 10 times, it loads approx. 27 gallons a minute. So still not even close to correct.

Surprise, surprise.

I did not change a thing. Just came back from a flight with the QW787-900. Result: in the tanks: Left 2,600 kgs; Center empty; Right 2,700 kgs.
I decided to top her up until 50,000 kgs in total. That means 17,433 in both wing tanks and 15,134 in the center tank.
Now refueling works like it should (at 10 time the speed as in the Settings).
 
Could it be, that when the fuel to be loaded is just for the wing tanks, so below 34,866 kgs minus what is still in the tanks, that this slows down the refueling proces?

In fact, that was exactly the situation several times with flights within Europe.

Please indicate precisely all the following:

- the fuel amount which was already on board BEFORE calling the GSX refuel

- if the airplane is configured to show the default fuel and cargo page or not.

- the precise, exact sequence of the operations you made, since calling the GSX refuel, both on GSX and on the airplane itself.
