Synchronous Buck Converter Gate Signal Offsett

Hello everyone,
In Figure 1, I designed a synchronous buck converter using the IR2110S half bridge gate driver integration. However, when I look at the gate-gnd measurements of the MOSFETs, I see that the voltages are offset. This situation causes MOSFETs to operate continuously and to be short circuited. Can you help with this?
