Academy has certainly never been widely-known for the...ahem...quality of its decals, flexibility and adhesion-wise, though my understanding and limited experience with the brand more recently is that the situation had improved somewhat in more recent years. Posts of other folks' issues have led me to pre-test individual kit sheets with a less-visible or easily replaceable decal from the sheet to start, then use Solvaset/white glue/Future applications as necessary---or just go with aftermarket markings, if all else fails.
Genuinely sorry for the loss of your decals, and hope you are able to find replacements.
