It is not uncommon for Cyms to miss a season after purchase because they are not getting the optimal care they received in the nursery they came from, especially if you might have kept them in the house too long while they were blooming and they got a slow growth start.
It is still a bit early for spikes to show on some of the later varieties. Red Beauty cultivars are not necessarily early up here in Northern CA. Yours could be just taking their time in a cooler zone than where they originally were grown. Cyms grow all year long so the continuing elongation of the new leaf growths is normal and a good sign. The spikes may just be late.
