I have opposite signs to dimension 1, dimension 2 and dimension 5

I tried this project, the explained variance is equal but I obtained different signs to my dimensions:

Dimension 1 Dimension 2 Dimension 3 Dimension 4 Dimension 5 Dimension 6
0 1.9083 -0.3765 0.1924 0.1502 -0.3852 0.5367
1 -0.0349 -1.6819 -1.7115 1.6613 0.5394 -0.1548
2 0.9955 2.3169 1.7454 -0.4569 1.2462 -0.0669

and the graph is opposite for dimension1, dimension2, dimension 5:
