Because Lincoln's plan had never been presented to the Congress. It was only proposed by Lincoln to the members of the Government on Apr. 11,1865, who repulsed it.
Louisiana was the sole State where the plan had been provisionally applied and, after the President was assassinated, it had been nullified, also because it was considered too lenient by the Radical Republicans who had the majority in the Congress and a part of the public opinion as well.

with whose plans did the radical republicans disagree
Abraham Lincoln's ultimate goal during the Civil War was to reunite the country. He felt that if the country was against itself, it would eventually crumble. He wanted Reconstruction, or the re-building of the country, to be as easy as possible (without slavery and with peace).The radical Republicans in Congress at that time wanted to punish the South at all costs; they had been traitors, and the Republicans felt that if they wanted to be readmitted into the Union, they needed to beg on hands and knees. Lincoln saw this, and it caused an abundance of tension and hostility towards the North. He wanted a very lenient Reconstruction process so that the Southerners would be more willing to compromise, and actually want to be readmitted. He thought that this way, the country would be able to rebuild more peacefully and successfully. Otherwise, the South would still harbor the same resentment they had before the war, and the country, in effect, wouldn't have solved its problems, and the war would have been for nothing.

Just an agreement to abolish slavery
One major area of disagreement between Abraham Lincoln and Radical Republicans is that Lincoln wanted to restore the United States by uniting North and South after the Civil War. Radical Republicans wanted to keep the South and North separate.
About the only thing that Lincoln, Johnson, and the Radical Republicans all agreed on was that the Civil War end expediently and the Union be preserved.
