"Renew" radius issue

It seems that regardless of the dungeon, the Renew skill often displays the radius incorrectly. When using and upgrading this skill, it doesn't matter what aspect you're upgrading - whether you're increasing HP by +3 or the number of activations to 1 or 2. The radius increases in size, but resets at the end of each floor, repeating this cycle on the next level and so on. Although this may not happen every time or in every game. The screenshot doesn't show the maximum size, there were larger ones, but I don't think it should be like that
