El límite no muestra la cantidad real después de implementar el contrato en la red principal de Ethereum

Desplegué un contrato de venta colectiva con etapas de bonificación en Main Ethereum Network usando remix.ethereum.org. He establecido una cantidad máxima de éter en wei como mi objetivo. Después de implementar el contrato, revisé los detalles del contrato para verificar la información como la dirección del token generada, los parámetros de fecha de inicio y finalización, la cantidad de éteres recaudados y la cantidad de CAP más importante que configuré en mi código (El objetivo de mi crowdsale). Ahora todo está bien. El contrato muestra toda la información correcta, pero el monto del CAP no es correcto. A continuación se muestra mi código de contrato de crowdsale.

Nota: este contrato de venta colectiva funciona bien en Ropsten Test Network y muestra la cantidad exacta de CAP, pero tiene problemas en la red principal de Ethereum. Cualquier ayuda será apreciable. Gracias
