As far as I've noticed it mostly pops up with Nanite Canister from the Miracle Worker specialization and the Shield Recharge from versatile kits as well as the new Soong Shield Drones skill, but it's possible there are others I haven't been able to test it with. I last noticed this bug way back in 2019, so surprised it hasn't been fixed yet.
Basically, NC and SR don't get the recharge reduction from Expedient Care, nor does the new SSD skill. They also don't seem to give the "To ally" buffs of the trait either. Miracle Worker skills like Harmonize Shields do get the recharge, but not the "to allies" damage resist and damage buff, however, yet the shield recharge does give the 'to ally' buff, but doesn't get the recharge reduction from other heals like Tricorder Scan being cast after it.
So Shield Recharge counts as a heal for reducing other heals, but cannot be recharge-reduced itself, while Nanite Canister doesn't count for reducing other heals or being reduced, nor does it apply the "to allies" buffs of the trait. Harmonized Shields is similar. It can be recharge-reduced, but neither gives the buffs nor recharge-reduces other heals.
Doesn't matter with what character or where, the trait simply doesn't work with those skills at least, possibly other healing skills.
