Copying automation between reverb plugins changes values

[Privyet]

When I attempt to copy automation data from the "decay" parameter of Dverb to the "time" parameter of "Reverb One", using Copy Special > Plugin Automation and Paste Special > To Current Automation Type, the automation data copies, expect that all pasted values are smaller than copied ones by 1.3 seconds. Acknowledging that these are two different plugins, the sound also clearly reflects shorter reverberation, weakly suggesting that this is not a purposeful reduction capturing differences between the plugins. The 4 starting and ending values in both parameters are identical before copy/paste. Any idea why this happens and how to prevent it? PT 12.7.0, very recent plugins. Thank you.
