I have already reported the problem here:

https://plarium.com/forum/en/soldiers-inc/bug-reports/104686_occasional-problems-in-the-tracking-tab-blocked-travel-lines--reports-do-not-arrive-/?post=495444 (here I expressly say that « it prevents me from using "instant callback" in the "tracking tab". »).
... but they ignored me, as if I were a newbie who does not know what he says.
me too, I use the tactic to callback my army a few seconds before it hits the target (if something goes wrong in the preventive tasting of the target), and I noticed that the button for the "instant callback" is missing when you send attacks and recons on the repositories ...
did you send some attacks on the repositories before this raid?
observing the phenomenon, I have discovered what the problem is:
What happens is that the banner showing the repository's tracking line, it hangs/sticks on the "Traking tab" (command HQ) at the top of the list.
From now on, all attacks (/ movements) that follow the blocked traking line, when they reach the first position, they are covered by the "traking line blocked" on top (like a mask covering the true traking line that is occurring).
The only solution that I found is to send a reinforcement to base near you, making sure that the reinforcement arrives at destination 1 or 2 seconds before the attack you are doing; in this way the reinforcement is placed between the "tactical missile "(which you send to taste the target base) and your true attack!
By doing so, your attack will not be at the top of the list after the tactical missile hits, so the reinforcement's tracking line will be covered by this bug, BUT NOT the attack's tracking line, which will be placed in the second row, allowing you to use the instant callback even when this bug happens in the "Tracking Tab", which sticks to the top of the list the banner related to the attack sent to the repository (which, when it occurs, the stuck "repo tracking line" covers all the first tracking lines that will follow!).
Now that someone has lost 10,000 zaams, I hope they will decide to take the problem I reported seriously and make some investigations.
As usual, "first someone has to die, and then measures are taken" (as a motto of my country says).
