different ul styles for different pages

I have previously added the following css to my stylesheet to make all unordered list bullet points to be a blue tick:

.entry-content ul li {
list-style-type: none;
}

.entry-content ul li {
background-image: url(https://www.oceanhomeloans.com.au/new/wp-content/uploads/2013/09/check-mark-blue-small.png);
background-repeat: no-repeat;
background-position: 0 5px;
background-position: 0 .05rem;
padding-left: 25px;
padding-left: 2.5rem;
}

Now I want one page to just show the default bullet:

I’ve tried a few different ways such as:

.page-id-175 .entry-content ul li {
list-style-type: disc;
}

and even tried with a custom body class, but the results remain the same,
the bullet appears but the blue tick remains.

Any assistance would be appreciated.
