It is devil incarnated.
Yes Im aware - however after the amount of kills, crits, caps, damage I should have had a nuke for what I did, however – On the screen with your line up ( where it shows the Nuke Plane) the values there are not increasing when a kill/cap or any form of points acrued.
Saw it sit at 647 with only 4 kills, made a further 4 with the cap and sat there with 647!
Wasnt until I died and got into a plane that the points updated Hence I believe the system isnt working correctly.!
Does that still happen after the most recent update?
If yes then that should be reported. You can bug report it here (just search a bit first so that you don’t report something that is already reported and known about): (Gaijin.net // Issues)
A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki)

@Necronomica - This is what I have mention before… the points don’t match, I didn’t even realise there was a drop down box on the screen indicating the nuke until I spotted it whilst getting close and thought what the heck is that all about.!
Ive probably missed a ton of nukes because of this stupid drop down box not being visible and instead checking the main launch screen multiple times whioch as stated isnt adding correctly… I said previously the vehicle screen isnt tallying up!
Also - I cannot submit reports.
I see at least one Light Tank in your lineup, I have a suspecion that the bug/glictch has to do with the reduction you get from light tanks (or any vehicle that has the “Airstrike” modification. There are a few SPG’s and SPAA’s that can scout and have the “Airstrike” modification too.)
IE, you are getting the correct & intended reduction to the spawn costs for your CAS/Nuke, but the point reduction is not being displayed properly (like you are experiencing, and took screenshots showing).

This obviously should have a bug report submitted. Why can’t you submit a bug report friend? Is it showing you an error code/message? @Necronomica is very knowledgeable about the bug reporting system, he should be able to help you work through the issues you are having with trying to make a report.
