After update to WordPress 4.9.1 slider works wrong


#1

I have updated to WordPress to 4.9.1.
Now header slider on start page works wrong. I have 3 slides with 3 titles. The images are changed. But with every image all three texts are displayed instead of the text changing. My site address is www.haus-lenzhalde.de. Can anyone help?
Best regards,

Hi people,
I am glad to solve the problem by myself. I changed from child theme Bistro to theme Sydney, customized it new and now it works fine!
