[LaRata]

1_ The su-25A do not seen the drop tank's ?

 

2_ 100 % Fuel in the editor but less in the su-25 ??

Everything correct, the first screenshot shows the fuel quantity including the two drop tanks (4100 kg), the second and third100% internal fuel (2900 kg).

To expand a bit on Volator’s answer, fuel quantity “P” on the left is the total fuel quantity. “T”, on the right, is fuel remaining in the feeder tank. When that starts going down, you’d better be close to home.
