Is "Cyclone 10 LP" slower than "Cyclone IV E" ?

I tested according to the same source code (VHDL) shown below. The reported delay was almost the same... but "Cyclone 10 LP" gave the following timing error @300MHz clock. Is my setting incomplete...

Upload screen capture.

But I'm not sure if it's okay with this screen, so attach the project folder (except db, incremental_db).

The timing report for all cases is in the output_files folder of the attached file.

If there is no workaround, does it mean that cyclon10E can not be used instead of cyclon4E in this situation (like 300MHz x 2 time resolution)?

I'm very curious that cyclon10E's Tco is over 1ns faster under these conditions(2.5V,8mA,slew=2).​
