First issue I see in Maple 2023 integrate

Example 1

restart;
int( (e*x+d)^(3/2)*(c*x^2+a)^(3/2),x)

Example 2

restart;
int((1+x)^(3/2)*(x^2-x+1)^(3/2),x);

Example 3

restart;
int((c*x^4+b*x^2)^(3/2)/x^(3/2),x)

 

Worksheet below for 2023 and also for 2022.2 showing this did not have this problem in 2022.2. Internally for me, this cause other problem when post-processing this, that is why I found it. Any one knows what caused it?  Maple 2022.2 result is much longer, but it does have this "undefined" issue in the result.
